Fatigue and lack of motivation on Prozac
I've been taking prozac for about a year now, and it has really changed my life. I have OCD that often left me in overthinking rumination, and the Prozac has significantly quieted my thoughts.
It is my first SSRI, so I started at 10 mg and slowly worked my way up. I'm currently on 40 mg which is a pretty low dose for OCD. I think because I have OCD (and not MDD), I don't necessarily feel emotionally blunted when on Prozac. But I do feel fatigued, and a severe lack of motivation.
Part of this is that, before Prozac, I had a hard time with staying asleep and would often wake up after only a few hours and ruminate until morning. I can now sleep through the night, and then end up taking naps. I also have a hard time waking up if I'm up late and need to get less than 8-9 hours. I've tried to switch to taking it at night, and that just gives me insomnia lol.
Also motivation-wise, before Prozac, I ran my life on a lot of adrenaline/panic/nervous energy, and I'm wondering if the "lack of motivation" I feel is more about not even knowing what my natural motivation/ambition feels like. Like, it's good that I'm not panicked all the time, but I also have some very real material issues, and those feel a little "whatever" to me at this point, and like ... I need to pay rent lol.
What I'm asking is: does anyone have experience with fatigue on Prozac? I am having a hard time communicating this to my prescriber because she insists that it's an activating drug and I shouldn't feel like this. But I do! In general, I don't have a strong response to stimulants (medically or recreationally), and I know most other SSRIs cause even more fatigue. Any thoughts or insights are very appreciated!
