I can see why you are bothered by it. I think there might be a better drug for someone like him, maybe like Trazodone or something like that. I hope he continues to stay sober and not drink with the Ambien. I think experiences like you describe leave us scarred for a while. It is hard to trust and it takes time to rebuild the trust. Is your AH in AA? I hope so. Everyone has stress and we all have to learn our own ways to deal with it. Unfortunately, life is not always easy..
