"i&#039;ve taken nuvigil off and on for about a year, along with 20mg lexapro. i take it as needed for depression and daytime sleepiness (i was falling asleep while driving). i find that it makes me agitated and irritable if i take it every day, so i only take 150mg when my depression is causing extreme lethargy and lack of motivation. 

when i do take it, it usually works within an hour. i am motivated, focused, and productive on this medication. it even helps with my social anxiety, and i find that i&#039;m more cheery and outgoing. i&#039;m more talkative too, but in a good way - not in a manic way. 

the problem? it wears off after 6-8 hours, sometimes leaving me with a headache. overall, however, it has been a big help to me!"
