"when i got prescribed ambien i started with 5mg and it worked but i only slept for 4 hrs. so the following night i took 10mg and i was asleep in no time and got a full 9hrs of sleep. best night ever in years. i woke up feeling refreshed. minor headache but i don&#039;t know if it was due to the ambien. 1 tylenol pill took it away so no biggie. this is the only sleep pill that has helped me. i tried restroil and seroquel and got no sleep only bad side effects. i love ambien."
