Should I be worried about taking Ambien?

I’ve read the horror stories, the weird side effects, the withdrawl, etc. But it helps me sleep, and that is golden.

I’ve come up with a routine of taking a full pill one night, half a pill the next night, and no pill the third night, then I repeat. Obviously, I sleep the best on the night I take the whole pill, and I haven’t had anything weird happen yet.. I’ve been going on like this for a month.

Any personal experiences with the drug here?
