Is it CHS?
I have smoked (mostly pens) on and off for the last 5 ish years, but when i was “on” i was definitely dependent/overusing. I usually don’t bring a pen with me when I travel and use it as a T-break. I might have trouble sleeping and eating for a few days but never anything serious. This most recent time I was find for the first 36 hours after last consuming, but around the 36 hour mark I threw up. I threw up all night but was fine the next day, ended up throwing up again a couple times the next morning but was fine again after that. I never thought I needed to go to the hospital since I didn’t get dehydrated, but I did consider going to Urgent Care just because my anxiety combined with cyclical vomiting was a nightmare. Also, I’ve always taken baths pretty much every day but especially when I’m not feeling well, so I couldn’t tell if that symptom was present. Thoughts?
