home for an island

I can't sleep anymore. When I try to go to bed I lay awake. It is too hot or too cold or I am not tired, but for whatever reason I don't fall asleep. When I do fall asleep I can't stay that way for more than six hours at a time. Saturday night I was out drinking and dancing until 3am; I woke up at 9am and could not fall back asleep. It happened again this morning, and now it's 2am and I've been in bed for an hour and I can't go to sleep.
