You switch by substituting over a period of three weeks. Start lowest dose of prozac, the start decreasing Paxil. Also, you can do something re emotional eating by going to masteringfood.com.
Absolutely DO NOT change or go off your meds without a really good psychiatrist. Don't try to do it through your regular m.d. and don't do it alone. I did try to get off of Paxil and could tolerate the zaps and brain fog but once I got down to 10mg from 40mg life became utter hell. I did this on my own and really wasted 3.5 months. It's dangerous to do it alone. I'm on Lexapro right now but will probably change to Prozac. I had no side effects from taking either one except for lack of libido and a general emotional flatness. When I say utter hell: zaps, brain fog, major anxiety attacks, extreme fear of being alone, insomnia (not just staying up all night). I've never had this type of insomnia. Everytime I woke up if I was sleeping my entire chest wall, neck, upperback would tighten -- I thought I was having a heart attack. It was worse in the day if I tried to nap.

Well I am going to be weaning off Paxil with Prozac and here is the schedule my doctor put my on in order to do that.
Week 1 Paxil 20mg + Prozac 10mg
Week 2 Paxil 15mg + Prozac 20mg
Week 3 Paxil 10mg + Prozac 20mg
Week 4 Paxil 5mg + Prozac 20mg
Week 5 Stop Paxil stay on 20mg Prozac
I have not started yet, but plan on starting it once I have vaction in 2 weeks, just in case I have any bad side effects from the prozac.
Hope this helps
