I am in the midst of exactly what you have decribed. I Have been completely off of Effexor for a few days now (I tapered from 300 to 35 mg) and have been experiencing depression which I HAVE never experienced like this before. I got on effexor to alleviate anxiety around my wedding over one year ago and I have been trying to get off ever since!!!!
The only thing that really helps me is to lie on the couch and drink hot tea!! If I try to run errands I can\'t drive b/c of the zapping going on in my brain......I recommend Green tea with a little sugar and milk..I swear it helps and hopefully this will all go away soon.
