aGrandma, does your husband's doctor know that he is an alcoholic? The only way this "agitation" will stop is for your husband to spend substantial time away from alcohol and other mind altering substances. Perhaps he should be de-toxing under a doctor's care. I think that I've read in some of your previous posts that there is an underlying "pain" issue with your husband...is there any way you could find some alternative treatments to deal with it? One of my friends was once addicted to vicodin due to a back injury. She began doing stretching exercises and yoga and they helped her immensely. At any rate, his doctor needs as much information as possible and if you think he's doing a poor job with your husband, you need to find another doc. I wish you the best.
Oops...I see that the doctor does know your husband is an alcoholic. Maybe it's time for a different doc...
