I have been on serzone for over a year. I took it at night because it caused severe abdominal pains for a little while after taking the pill(even on a low dosage). Otherwise it was pretty good.Because of the recent warnings on liver damage I asked my Dr to put me on something else and he suggested celexa. I am decreasing the serzone dosage but because it was only 100 mg to begin with, I moved to 50 for the first step and only step before stopping it.How long will the headaches, jitters and various other symptoms last? I want to start the celexa soon, but would like the worst of this to subside first.Help!
