"i have been on it a few months, with great results for my add. i have greater concentration and am up getting things done, instead of vegging in front of the tube. the major drawback has been sweating. i was getting chills and sweating a lot! originally thought it could be hormones, but not after reading others&#039; comments matching my symptoms. i was jittery at first, but now smooth sailing. i tell lots of people how happy i am with the results. i loved welbutrin but am allergic."
