I used to be on Paxil (which is called Seroxat or Paroxotine over here in the UK). I tried over 9 months initially to come off 30mg (having taken it for about 4 or 5 years beforehand but being rubbish about actually remembering to take it every single day). I stopped at Christmas, by February I was feeling suicidal and was admitted to a psychiatric hospital because of this. I left and a few months later went back onto Seroxat.

I did a bit of research after this I then found out that the drugs have a half-life of about 2 days but can remain in your system for around 1-2 months. Which could be why I slowly became worse before landing myself an admission.

I did come off in the end (I went back on to Seroxat a few months later for a few years) and the second time reduced down from 20mg over 18 months and managed a lot better even if I got side effects for much of that (physical side effects rather than mental or psychological).

I can't help wondering if the reason the initial 9 months wasn't enough was not because I was reducing too fast as much as any residue left in my system would have been depleting too fast and along with my intake reducing was just too quick. I'd advise taking your time reducing that particular a/d because it wasn't easy despite the very positive set-up I had at the time.
