i seemed to have insomnia all my life. ambien worked somewhat, so did seroquel, lunesta made me more suicidal. everybody questioned the caffiene, the energy drinks, but it didnt seem to matter, i cut them off in the afternoon and i would still be up until four am. turns out that i am so hypersensitive to caffiene, that if i have it early in the day, it still is keeping me up till four am so i had to cut it out completely. now i find i need to sleep 10 -11 hours a day to feel good. but i go to bed and I actually fall asleep within a half hour without drugs, big difference.
