Were you weaned off the Effexor gradually? If so, the withdrawal symptoms are usually not too bad. If however you stopped taking the medication abruptly you would experience terrible withdrawal symptoms. If it's been 3 weeks, you have probably already been through the worst of it. Just hang in there, you will start feeling better. It does take time.
My doctor weaned me off Effexor over a relatively short period, about 3 weeks and then I was done. I didn't have any side effects from not taking it. I would suggest calling your doctor because your reaction sounds more difficult than it should be! I wish you all the best ... take care!
Hi I have been prescribed various antidepressants, and from experience I know that not all medications agree with the individual, certain meds make you feel terrible when you first start taking them, they say it will eventually get better, but I have never stayed on a med for more than three weeks if I didnt feel ok with it. Maybe you should see your doctor and try another medication, although stopping effexor can make you sick too, from withdrawls.
