at 3:30am and has continued and even worsened since then. She had surgery perhaps 5 years ago and wound up in an ER and was later taken to a mental institution for a few days. I can't do that to her again. She snapped out of it by the next morning and didn't know why she was there. In the meantime I am worried sick and have no idea of how to help her. She won't drink water or eat any food. She was rational for a little while this morning and asked for a Valium to calm her down which I gave her and now regret. The Valium was taken 9 hours after the dose of Ambien. Following surgery she typically struggles to sleep and was sleep deprived for two days before taking her first and only dose of Ambien. What do I do now?
