well ambien isn't meant to keep you asleep, just knock out out. its a short acting nonbenzodiazipine. The CR version may work better but as i mentioned i've never tried it.
the problem is that if u have any benzo tolerance, it carries ove to the zdrugs and vice versa. so if u take benzos now and then you may find that a normal dose, 10mg ambien just doesn;t cut it. At that point its tough because asking your doc to rx u more is only going to prolong the problem in the long run.
benzos are great, but they also suck. tolerance goes up and up and up...
my fingers are crossed for some of the new research going into orexin/hypocretin receptor targeting drugs.
wish i could get in on a clinical trial or something
