Sorry to hear that things are going so rough on the Effexor detox. I was in the same boat about three weeks ago. Mine wasn't as bad as yours, but it was annoying nonetheless. I actually had a doc appointment yesterday since I was still feeling pretty gross. He was surprised that I was still nauseous after 4 weeks, but he sent me for blood tests. He was saying that sometimes it throws off other chemicals in your body as you're coming down and there are some treatments that help to reset the more acute imbalance and make the 'discontinuation' a little more bearable.
I've also read, and I think that one of the Shannons posted with some help, that a single dose of prozac can sometimes help to offset the discontinuation. The long half life of the prozac helps your body chemistry overcome the withdrawl of the Effexor which has a really short half life.
I was prescribed Effexor after being first diagnosed with unipolar depression and at the time the Effexor was a god send. It was ultra irriating to get off, but I'm glad that I had it for the really dark days. I took it for two years, and am now at a place where I am stable with depakote. I anticipate that at some point, I will need to take another anti-d and I've talked with my Dr and he agrees that it is not likely to be another SSRI-type drug.
