I've been on Ambien for years and take 20-30mg a night along with a host of other drugs. Be most careful about the day after forgetfulness and be extra sure not to leave your house after taking the Ambien. Take it and go to bed fairly soon after because it usually makes you go to sleep fairly quick. Let me know if I can answer anything else about it, I've taken it since it was a new drug and even tried Ambien CR but didn't like it as well.

Take care,
Lori
