Did your DH sign a release giving you permission to discuss his treatment and meds? Many vets do NOT allow their spouses privy to the info. With my vet BF, it was a "sign it or take a walk". Seriously. I don't want to be the last one to know, and suffer the blowback, if his issues and meds are not being addressed. With his bipolar, PTSD, and panic disorder, it's an incredible amount of issues to deal with even when he IS taking his meds as prescribed. The incredible amount of benzos he was prescribed over the last 17 years have caused extreme forgetfulness, DANGEROUS forgetfulness, something that is a constant. Even with his slow reduction in the last 6 months, it's irreversible, and possibly will culminate into dementia. The lithium makes him tired, unmotivated, and prone to eating far more than he should, and not healthy food at that.
I still don't have a valid explanation for the bevy of tests they did over the past year to find if he suffered from Alzhiemers. All I got from his "nurse" was that the found "spots". Maybe caused by his alcoholism 17 years past, maybe from his age, 65, going on 66.
Marriage is an "iffy" subject". Been with him, going on 11 years, and I just don't know.
