I take venlafaxine for migraines and and of the many drugs I’ve tried, absolutely nothing compares to the withdrawal symptoms for venlafaxine. They start 12 hours after missing a dose and doctors have no official designation for them, besides being insanely nasty.

Please for the love of all that is holy, if you are on venlafaxine and want to switch to something else: titrate. Not all doctors know about the withdrawal problems with venlafaxine. They are horrendous.
