Budeprion and lethargy

I was taking Wellbutrin for about 2weeks (i had taken for about 7yrs previously) from Effexor because of sexual side effects. The Welbutrin worked to get rid of that problem and my Dr in the hospital warned me about generic Budeprion, but my regular PA-C said that the 150's were different and made by Glaxo. Huh???? Like an idiot i got the generics and 5 days later I feel like i have no anti-depressant in me. Im having panic like "emotional attacks" where i just cry if I hear or see something that triggers an emotion, sleeplessness (i don't need any more of that), weight loss (what's food and why is my stomach gurgling) and over all lethargy. I hate this drug, its useless beyond belief, I really wonder who got paid at the FDA to pass this one through.

I gave this medicine several weeks of a chance to help me out. I am not a day sleeper, but I experience lethargy and I have taken naps a couple of days in the week, even after drinking several caffeinated beverages. I will be out of my samples Tuesday. I am going to have to fight my insurance company to get the regular Wellbutrin XL now. The depression I experienced was because of the tiredness.
