Budeprion better than Buproprion?

I started 150xl budeprion and read all the comments about it being worse, FDA approval, more side effects etc. I actually felt high the first week and then I just felt so much better; I didn't realize how depressed I was. Then my doctor and I agreed to increase to 300xl so I took two of the 150xl budeprion in the morning. I felt a little high but much better so I told her to go ahead with writing for 300xl. I got my rx and the pharmacy gave my 300xl bupropion (BUPR) not (BUD). I noticed i was anxious and my heart was racing. I started feeling depressed again and having hopeless thoughts. Now I am waiting for the pharmacy to fill the budeproprion by teva that it seems everyone had such a hard time with. Has anyone else had a better experience on the TEVA BUDEPRION or am I just making it up in my head?
