Pain
"Please be very aware of the side effects. I was taking this with no problem for about 6 months, then starting having mini blackouts (10-20 secs). Blacked out at the wheel and at work. Apparently this is called mircosleeps and is a possible side effect (under Somnolence). I also experience the CNS Stimulation side effects- mostly anxiety and euphoria. I have been off it for 6 months and no issues, but my doctors had no clue it was the medication, until I stopped taking it and the problems went away."
