I went cold turkey on Effexor, I was taking 225mg @ day. I thought I was going crazy too. I was taking this dose for the last two years. The shu..shu..shu in my ears, feeling feverish/stoned all the time, sweating, pin-headed pupils...a trip to HELL! I guess the misery loves company and it is quite a relief to know others have the same malady. I know that I can make it through the withdrawls now.
