"this worked great for my adhd symptoms. my family noticed an immediate improvement. i did get a little bit of weight loss, but that was good for me (38 years old). my biggest problem was that it caused erectile dysfunction and a strange lack of sensation in my prostate area, even at low dosage (18 mg/day). it was sufficient to stop use.  i am on adderall xr now which doesn&#039;t do nearly as well.  my doctor is going to try me on some antidepressants as they also influence the norepinephrine levels.  if you don&#039;t get the erectile dysfunction then this is a great medication."
