I'm very sorry for your situation. In April I tried to commit suicide. I used a bottle of klonopin. It was not that this particular drug was preferred by me; it was just what was available. I guess what I'm trying to say is the ambien is not the problem. Your husband needs to find a way to deal with his stress. I found a wonderful therapist, and I started walking. I tell myself it will never happen again, and my husband worries too, but the partner of the ill person can only do so much. The rest is up to him.
