"i&#039;m on my 5th day of starting welbutrin sr (generic) 100mg and feel more energetic and less depressed and lethargic. that could be a placebo effect so early in treatment, but i know for sure that its almost completey taken away my appetite.  i actually forget to eat. i had been on prozac, which worked great at first and then the therapeutic effects seemed to fade over the months until i was severely depressed again.  this has happened to me with several other antidepressants as well.  i hope that welbutrin will work consistently for me.  so far i&#039;m very happy with the results."
