I was married to a nam vet also. he had severe ptsd and drank wayyyyyyyy too much.

maybe talk to his dr and get them to order home health care and go from there with getting you some help. don't feel guilty for asking for help either hon. make sure though whoever you can get that they know about combat ptsd and alzhiemers. they should be able to provide you with respite care too so you can have some ME time. keep us posted and welcome to the group. oh btw does the vet center he goes to have a spouse support group as well? Please get some kind of counseling for yourself too.
