paxil has a short half life. you might not want to do it that quickly! take your time.
I was on 100 mg's of zoloft and although it is a completely different med (and half-life, and dosage) I did something like this:
week one:
100-75-100-75-100-75-100
week two:
75-50-75-50-75-50-75
week three:
50-25-50-25-50-25-50
week four:
25-12.5-25.12.5-25-12.5-25
week five:
12.5-0-12.5-0-12.5-0-12.5
etc..
It is best to take your time and do it slowly. The serotonin center in your brain has had "free crutches" for awhile now, so it takes some time for it to balance itself out toward its natural healthy functioning state.
