ah i know i just posted, but i forgot to ask about something else. my primary doctor told me that ambien and the other sleep meds wear off after a time, and don't work as well. has this happened to anyone? i was on ambien, but all of a sudden i couldn't sleep anymore. i've been having to take nausea meds with the ambien so i could actually fall asleep. and now they switched me to lunesta, which seems to work even less. i'm not getting to sleep early enough, so i'm sleeping in until about noon. i usually NEED twelve hours of sleep to function, and i feel sick alot at night from lack of sleep. has anyone experienced this and found a solution? i can't stop the sleep meds, or i don't get to sleep until five in the morning, and then i only sleep for three hours. help!!
