i would get OCCASIONAL headaches with Ambien (regular release), as well as with either of the two benzo hypnotics i had. mostly if i took something and then had to get up after insufficient sleep.

i would suggest using it on the weekends at first. and ensure you are going to be undisturbed until you are ready to get up, at least until you have a better idea of how you get along with the med, and know how much sleep you need with it. the package insert says get 8 hours - i did not always get that, but get as much as you can.

i should add though, that i can get sleep deprivation headaches without taking any drug. i don't wake up with the headache in that case - it tends to hit later.
