I\'ve noticed some major hair loss too for the past 5 or 6 months, and had no clue that there was a connection until reading these posts. I\'ve been on 300mg xl for about a year or so. Thankfully, I just happened to have stopped Welbutrin about a week or so ago because of other side effects (tremors and numbness in my arms and hands). Anyway, some of the hair is still falling out, but I hope it\'ll stop when it\'s completely out of my system. If you\'ve noticed hair regrowth after stopping this drug, please post on this board. It would be nice to hear that people\'s hair does grow back after being on this nasty stuff. Oh, and if there is a class action law suit going on due to this, please contact me. I\'m in! Thanks!
