depression
"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't work for me."
