Thanks so much for your responses.
Good to know it's ok to take once a day in the am.
Are you able to sleep? I' was on ambien even beofre and my doctor just changed it to ambien CR thinking it might help me sleep longer. It doesn't work unless I take two of them. I've read a controlled study that says rifampin decreases it's effectiveness by 58%.
A pharmacist told me that taking more ambien (zolpidem) is not abusing the drug because rifampin changes your liver enzymes and it just doesn't all get used. But my MD told me not to take more than one.
Yes Hugh, I'm concerned also about my thyroid med which of course if a hormone. I wasn't told that I should get checked in time. Actually, I'm tired in a different way now and actually wired so if I'd get tired from low thyroid and could sleep that would be wonderful! But not sure if it would work that way.
ecotick, I'm taking it with doxy. Sorry to hear you got insomnia by "nerve" symptoms do you mean anxiety? Do you mean you were symptom free for 3 months during the 5 months on it?
