What I'm about to say is based on MY experience only. Please take it with a grain of salt.
Back in December, I decided to stop taking my Prozac cold turkey. I was on the lowest possible dose of 10mg and Prozac is meant to be the easiest drug to come off of as it had the longest half life. I was on it since I was 14-15, so about 4-5 years.
About three weeks after stopping it, my anxiety reached its peak. I used to only have anxiety attacks a few times a year when I was very stressed over school and exams. However, the withdrawal symptoms I got from Prozac were horrible. It was hands down the worst experience of my life. I started off having horrible anxiety attacks and insomnia. I went TWO days without sleeping which is unheard of for me. I'd lie down and my heart started pacing and I'd feel like I was dying and had to get up ASAP. I'd have random bursts of crying and would pace around the house all day.Ii then began to wake up with migraines that ended up lasting me just over one month. I went to bed with these migraines and 'woke up' with them (keep in mine I was barely sleeping so they were 20x worse). I remember feeling so distant...as if I wasn't really in my body, but watching from afar. It was one of my scariest experiences yet. I couldn't handle it and had to go back on my medication ASAP.
I'm still on it now, and have been on it since January 22 as I couldn't handle the withdrawal. I'm now about go taper off of it very soon by using a syringe to liquidize my medication in order to go down from 10mg to 9, 8 etc as I'm already on the lowest dose and this is the only way to do it.
I'm not a doctor, so please don't take this too seriously, but I would never recommend going on antidepressants/anxiety medication long-term.
I know this isn't the advice youre looking for, but going on Prozac is one of the worst decisions I made. I recommend reading this forum
