Anyone else made this switch? What were you're experiences?

I was taking 300mg of Bupropion HCL (Welbutrin) - 200 in the morning and 100 at noon. I asked my pdoc if there was something I could take just one time per day, so I'm trying out taking 300mg of Budeprion XL in the morning. It has only been a week so I'm not sure if it is too soon to see any change. However, I felt a little nausious (please don't be the flu) and I have less energy/more depression.

My pdoc says that people have reported that Budeprion XL doesn't work as well as the name brand Wellbutrin XL. I'm going to try the generic for a month and if it doesn't seem to be working pdoc says I can switch to the name brand.
