"can&#039;t sleep like a normal person due to a circadian rhythm disorder - without this med i would get one or two hours of broken up sleep a night, total. i would probably be institutionalized or dead if it weren&#039;t for this medication. it used to make me feel groggy in the morning but i think i got used to it. i also drink strong black tea and take adderall, which counter the side-effects almost completely. i&#039;m not 100% functional still, because it does knock me out and leaves me slightly hungover, but it&#039;s a small price to pay to sleep mostly like a normal person where i was not sleeping at all. on a good night i get 7-8 hours and wake up once, sometimes not at all. cutting out coffee has helped tremendously too."
