"well, for the longest time i was on 20 mg and i felt okay. which was a lot better than the constant anxious mood i was in and i could finally go to school. the last 3 weeks, i was on 40 mg after trying wellbutrin and having a terrible reaction to it. but in the two days that i came off of celexa, only taking 20 mg again, i had the worst withdrawal symptoms. it might work for you but after a while it didn&#039;t work for me."
