About three weeks ago I finally finished weaning myself off of Effexor. I had been taking 300mg daily for about 10 years and gradually cut my dosage back over an 8 month period until I was taken one-quarter of a 37.5mg tablet once a day. I stopped that 3 weeks ago. Throughout the whole weaning process I really didn't suffer any serious withdrawal symptoms but now I am having a bunch of problems. I can't sleep (I still take two sleep meds), I have periodic nausea, headaches, lightheadedness, foot and leg pain, fatigue, headache and excessive sweating including night sweats. I'm guessing these are all a result of my body's biochemistry and physiology needing time to reset itself to functioning without that drug and that it's just something I'll have to live through. I am wondering if anyone has any idea how long I can expect this to last. Weeks, months? Are some of the side effects of the drug permanent, like the essential tremor I developed?
