I was on it for 7.5 years at 75mg daily.
I vaguely remember going up to 150mg for a short while but it made me very sick.
After seeing a brilliant counseller last year i decided to start weaning off it, so i dropped to 37.5mg per day.
After a week or two of feeling pretty bad i did improve -i felt more alert and more 'me'
I took this dose for about 9 months, but started feeling light headed, tired and just not right.
After a few failed attempts to cut down some more by breaking up the pills i have managed to withdraw now using Fluoxetine.
My last Venlafaxine pill was 2 weeks ago.
I'm now withdrawing from the Fluoxetine, but thats a different story for another thread!
