Hello-
I am taking 37.5 mg of venlafaxine. I have been on it since March 2015 for treatment of migraines caused by a concussion. My doctor said I could try going off now (no migraines since May) because we want to start trying to conceive again. I could tell that withdrawal wouldn't be easy from a dizzy/vertigo feeling and headaches I get when I take a dose a bit late. I also had a hard time starting the drug- not sleeping for 3 days and lost 7 pounds.
I started taking it every 36 hours, but was feeling quite groggy, no attention span. I found this forum and saw that is never recommended
