I was on Venlafaxine and yes the withdrawals were crazy intense. If you do go on them and for some reason not work please please please take it very slow when weening yourself off of them. I also noticed that if I didn't take them exactly 24 hours of each other I was already feeling the withdrawal symptoms. It didn't work for me but doesn't mean it won't work for you. We are all different in how meds affect us.
