I was on prozac for a year and a half a while back at 40mg a day a.d stopped cold turkey. I didn't consult this with my doctor, which is never the smart thing to do. This being said, I did not experience any noticeable withdrawals other then a slight headache for some days after as well as slight difficulty sleeping. It was a very easy med to stop for me.
I was later put on 300mg of effexor and was on it for 6 months. This med was very bad.for me. It caused worsened depression and left me feeling lethargic and nearly emotionless. My doctor began tapering me off 2 weeks ago and in 12 days was down to 0. This was a very very very fast taper for a drug.like.effexor. it left me with cold sweats, the shakess, nausea, and last night I had a 2 hour period of full blown audity hallucinations unlike anything ive experience from hallucinogens ive taken ( Lsd, 25i NBMOe, 2C-b, 2C-c, and dmt) It was quite scary, I had loud voices suroinding me like I.was at a party, as well as dogs barking, and random notices of things falling. It was not pleasent.. I guess that's what happens when you taper off a drug that is said to have the worst withdrawal effects over only 12 days when they reccomend a number of weeks too months.
