Update, after 55 days on 100mg sertraline
I want to document my full experience after increasing Sertraline (Zoloft) from 50mg to 100mg because during the first weeks I genuinely thought I was losing my mind. Reading detailed timelines from other people helped me survive those weeks, so I’m posting mine in case someone else is going through the same thing.
Before increasing to 100mg:
I had severe insomnia
Sleeping around 4 hours
Constant panic
Crying every day for around a week and a half
Severe fear
Morning terror
Anxiety about sleep
Intrusive thoughts
Fear of losing control
I was in a really dark place mentally before the increase.
Day 1
Extreme fear, panic, intrusive thoughts, and severe anxiety after increasing to 100mg.
I had a terrifying feeling of losing control and felt mentally overwhelmed almost the whole day.
Day 2
Still severe panic and anxiety all day.
Fear of losing control continued. Constant adrenaline feeling in my chest and stomach.
Day 3
Morning and evening were horrible. Strong fear, panic, intrusive thoughts, chest tightness, and a feeling of mental doom.
Day 4
Severe fear and panic again.
Morning anxiety was unbearable. Evenings were slightly less intense but still very bad.
Day 5
Morning intrusive thoughts and anxiety continued.
However, I noticed my first “window” of relief: From around 5 PM until almost 11 PM I felt calmer.
That small window gave me hope.
Day 6
Probably one of the hardest days.
Morning anxiety was 100/100. Sweating. Intrusive thoughts. Fear. I felt frozen in bed and almost scared to even shower.
It honestly felt like the intrusive thoughts were stopping me from functioning normally.
After taking a shower, praying, going outside, and sitting with family, the anxiety slowly reduced.
I also noticed:
I became afraid of being alone
When alone, intrusive thoughts attacked harder
I wanted to stay near people
At this stage, when I was anxious I couldn’t even enjoy games or move from bed.
Day 7
First noticeable improvement.
Morning anxiety reduced slightly. The intrusive thoughts became less “sticky.” Fear dropped maybe 10–15%.
This was also my first day taking Gabapentin 300mg. I felt slightly calmer and emotionally softer.
Still had:
Fear in the evening
Anxiety
Intrusive thoughts
Xanax helped only partially
Day 8
Anxiety was still there but clearly less than previous days.
Intrusive thoughts also started reducing.
Day 9
A calmer day overall.
Still had:
Morning anxiety
Panic sensations after waking from sleep
Fear around sleep
But during the afternoon:
No intrusive thoughts
No major anxiety
I could sit alone comfortably
My watch even gave me a “high stress” notification but emotionally I actually felt calm.
I also used breathing exercises which helped.
Day 10
Woke up with mild fear but no intrusive thoughts.
Still had anxiety around naps and sleep. Used breathing exercises and anxiety reduced.
Intrusive thoughts were weaker now. I started recognizing: “This is OCD/anxiety, not reality.”
At around 2:30 PM I experienced a strong calm window: No anxiety. No intrusive thoughts. Just peace.
Day 11
Sleep became fragmented again.
Dreamed about failing school exams and begging teachers to pass me. I think anxiety was expressing itself through dreams.
Morning:
Anxiety
Broken sleep
Fear around sleep returning
No major panic though.
Day 12
Morning anxiety again. Calm afternoon. Sleep anxiety returned at night.
Day 13
Morning fear continued but less severe.
I kept obsessing:
“Will this medication work?”
“Will I go crazy?”
“Will I recover?”
But interestingly: I started wanting to play League of Legends again.
That was important because during the worst anxiety I had zero interest in anything.
Day 14
Mild morning anxiety.
Waves of fear came and went during the day.
Main thoughts:
“Will I recover?”
“Will I stay like this forever?”
I also started monitoring chest tightness and bodily sensations constantly.
Some moments:
I wanted to play games
Other moments: I forced myself because anxiety killed motivation
Day 15
Woke up with fear again but less severe.
The intrusive thoughts changed: Instead of terrifying thoughts, it became: “What are you going to do today?”
Almost like leftover anxiety patterns.
Important observation: When distracted, symptoms improved dramatically.
At noon:
Calm
Wanted to watch shows
Wanted to go outside
Wanted to sleep normally
Comfortable being alone
That was VERY different from the first week.
But later after a nap: Sleep anxiety returned again.
Day 16
Morning:
Anxiety
Didn’t want to be alone
Fear around previous night’s sleep
But after sitting and talking with my mother, the fear disappeared.
At this stage: The anxiety became centered mostly around sleep, not general terror.
Day 17
No major anxiety upon waking.
Still had:
Disturbing dreams
Fragmented sleep
Hypnic jerks while falling asleep
The hypnic jerks became a mental trigger for me.
Day 18
No morning fear.
15 minutes after waking: Sudden intrusive thoughts and mental hypervigilance.
It felt like my brain was “waiting” for anxiety.
But emotionally: The panic itself was much weaker now.
Day 19
No morning panic.
Main obsession: My smartwatch sleep data.
If I saw: “6 minutes deep sleep” it immediately triggered chest tightness and fear even though logically I knew the watch is inaccurate.
I also became obsessed with:
Naps
Sleep timing
Whether I should sleep more
Whether hypnic jerks would return
But after taking a nap: I became calm again.
Day 20
Major improvement.
I realized my watch was inaccurate and my mood became calm instantly.
This was one of the first days I truly felt: “I’m becoming myself again.”
No major intrusive thoughts. Enjoyed games, shows, food, and normal life.
Still had fear: “What if I lose this calm feeling?”
Days 21–24
These days were mixed.
I noticed:
Anxiety spikes after poor sleep
Anxiety after unusual events
OCD attaching itself to sleep quality
Fear of naps
Fear of sleep paralysis
Fear after hypnic jerks
BUT: Compared to Week 1: The intensity was dramatically lower.
Some afternoons felt almost completely normal.
I also started practicing ERP and CBT more seriously:
Labeling thoughts as OCD
Refusing reassurance
Accepting uncertainty
This helped a lot.
Days 25–31
Huge improvement period.
Some mornings:
Zero anxiety
Zero intrusive thoughts
Felt completely normal
Motivation returned fully
I genuinely felt like: “My old personality is back.”
I wanted to:
Study
Go out
Play games
Exercise
Socialize
Sleep also improved:
7–9 hours
More continuous sleep
Less panic before bed
However: Occasional anxiety waves still appeared during evenings.
Days 32–38
Mostly stable.
The main remaining issue: Sleep OCD.
Examples:
Trying to force sleep
Monitoring sleep hours
Fear after naps
Fear after fragmented sleep
Fear of not sleeping enough
I also stopped morning Xanax around this period and noticed temporary rebound anxiety waves.
But overall: Life quality was MUCH better.
Days 39–45
Another major improvement phase.
I started thinking positively about the future again. Even my fear about psychiatry as a specialty reduced dramatically.
At the beginning of treatment: I was terrified psychiatry would worsen my condition.
Now: I actually felt excited about psychiatry again.
Some days felt almost euphoric:
Calm
Motivated
Hopeful
Enjoying life deeply
But OCD still searched for “targets”:
Fear of medication dependence
Fear of routine changes
Fear of relapse
Days 46–50
More stability overall.
The anxiety no longer felt like pure terror.
Instead: It became waves.
Triggers included:
Poor sleep
Naps
Physical sensations
Sciatica pain at the gym
Thoughts about the future
Fear of relapse
But even during anxiety waves: I remained FAR better than Week 1.
Days 51–55
This stage surprised me.
I discovered something called a “theme shift.”
The original terror and sleep panic became weaker. But the anxiety transformed into something else:
Fear of emptiness
Fear of free time
Feeling uncomfortable being alone in the morning
Restlessness
Feeling mentally “on edge”
Feeling like I wanted to run away but didn’t know why
Day 55 especially: I woke up after 6.5 hours sleep. No panic attack before bed. Fell asleep quickly.
But in the morning: I suddenly got a very old feeling from Week 1–2:
Restlessness
Feeling unsafe emotionally
Fear of emptiness
Wanting to escape
Not wanting to be alone
What confused me: I was actually outside with my brother at the mall.
Then by afternoon: The feeling faded and I felt normal again.
That experience taught me: Recovery is NOT linear.
What helped me most
ERP
CBT techniques
Labeling thoughts as OCD/anxiety
NOT arguing with intrusive thoughts
Going outside even when anxious
Gym
Staying busy
Family support
Prayer
Accepting uncertainty
Stopping reassurance behaviors
Understanding that setbacks happen
Biggest lesson
SSRIs healing is messy and non-linear.
You can:
Feel normal one day
Get hit by anxiety the next day
Have old fears temporarily return
Develop new anxiety themes
That does NOT mean you’re back to the beginning.
Compared to the first 2 weeks: My condition improved massively.
If you’re reading this while suffering during early Zoloft adjustment: You are not alone.
