Budeprion and heath

I have been on Wellbutrin XL for 2 years with no ill side effects and it has worked well. 2 1/2 months ago my script changed to the 'generic' BudeprionXL. Since this change, I have been experiencing severe muscle and joint pain, my hands go numb, my skin crawls to the point that I have scratched myself to the point of bleeding. Sleeplessness has just recently started to occur and my teeth have also become very sensitive. General irritability has also set in. I have not yet started to get the headaches most get with the Budeprion and it a good thing as I'm already taking 1600 mg a day of Advil to try and arrest the muscle and joint pain. After reading these other ill effects of this drug I'm now very scared and will be calling my doctor to get her to represcribe Wellbutrin -only- 'no generic'. It is clear to me the FDA did not do the proper research or makes me think TEVA has a friend in the FDA's office.
