Budeprion and stomach pains

Wow!!! Should have done my homework when they switched me to this nasty Budeprion!!! I have been on Wellbutrin XL for over two years, after being on quite a few other drugs for depression, with great results and absolutely no side effects. Then about two months ago my insurance company would only pay for the generic, so unless I wanted to pay a lot more for the Wellbutrin, I decided to switch. This was also after many phone calls and being assured by the pharmacist and the nurses at my doctors office that it was the exact same drug. I have had lots of trouble with generic drugs in the past, and this is why I was so leary to switch since I was doing so well. For the last week I have felt like absolute crap! I have had a constant headache, nausea, stomach pains, indigestion and lots of crying!!! Never in a million years did I think it was the drug, since it is suppose to be the exact same make-up and I never thought it would take two months to feel these terrible side effects when I never had any before. Sure wish I had come across this website two months ago. I have fibromyalgia as well, and thought a lot of the additional joint pain and numbness in my hands was from that, although I have had my fibro under control for a couple of years now. Thinking back now over the past few months and all the crazy symptoms I have been having, it all makes sense!!! At least I know I am not CRAZY and hopefully I can stop this nasty drug and feel better soon. How can this Budeprion be on the market and how can pharmacists tell people that it is the same. Now I have to fight my insurance company, and hope they will pay for the Wellbutrin.
