Did you slowly taper off the drug? This is a very hard drug to stop taking without suffering withdrawal, and you are describing common withdrawal symptoms. There's no way to know how long it will take to go away -- it's a very individual thing. For most, it goes away soon if done properly, but for some it can take a long long time. That's why you want to do it the safest way, so you don't get that problem. If the effects are more than you can handle, or if you're getting emotional problems you never had before you went on the drug, I'd go back on it at the last dose that felt fine and taper off as slowly as you need to until you successfully stop the drug. If you decide to wait it out, hopefully, it won't last long, but there's just no way for anyone to tell you what your experience will be.
