"the first few days while taking wellbutrin,which is not really recommended for anxiety but doc recommended giving it a try, were not too bad.  around week 2 i began to notice i was miserable, angry all the time, and just not feeling like  myself!  i am usually a happy person that laughs alot and enjoys making others laugh!  wellbutrin changed all that!  i was now a bitter and angry person that found fault with everything!  i wasn&#039;t sleeping well, had slight headaches everyday and my head felt cloudy and foggy all the time!  i wasn&#039;t able to concentrate which made it difficult for me to function properly at work. i was no longer the happy,silly person i used to be!  this drug totally changed my personality!"
