AMbian CR seems to irritate my stomach in the am. I took it and found it only helps me for abuot an extra hour or an hour and a half. I'm looking for an entirely different true long-acting sleep aid that is strong like Ambian now. I swear there have to be old standards besized trazadone out there that helped people in the last few decades that can be purchased longer term and used, and I'd pay less. I'd like to have one to use later on when I'm all done being treated or my whiplash injury.
