I'd just like to warn everyone that it causes really bad effects in some people, and it might be hard to tell if they are. Using the med in the short term should be okay like they say, but that is part of why I didn't realize the problem. I'm very sensitive to meds/etc but I thought zolpidem was working well for me, I liked the ease of falling asleep, and I didn't think I was having any bad effects. The first week or weeks I probably didn't have much adverse effect, but then it caused me major issues. Now I realize that being on it daily been causing this downhill decline which I thought was just some worsening of fibro fog and fibro. I felt like I couldn't think or use my memory recall, and I was going crazy. This link has bunches of other people writing about bad effects they got, including some talking about suicidal thoughts: http://drugs.healthdiaries.com/ambien-side-effects.html and I agree with them that it was really ruining my life.
