"nuvigil is a great medication. i have bipolar disorder mixed state. i was often drowsy before taking nuvigil. the first few days of taking 250mg of nuvigil i felt better than ever. i was working out at the gym for an hour. before taking the medication i couldn&#039;t even run. depression sucked the life out of me. one of the bad side effects of nuvigil is it induces mania/hypomania. i became hypomanic until my mood would drop down to depression and i had to take a mood stabilizer in order to normalize my mood."
