Hi V,
Oh gosh, it's so tough isn't it? My husband's pulmonologist said the very same thing. That my hubby, even though his SNIF is 15, could last years on being that low. I'm tired, too, and the thought of several more years of caretaking scares me. My husband, however, wants to live for years to come even if all his faculties are taken away. Because I know he wants to fight to live so badly I, of course, support him, even though the thought exhausts me. I'm not sure what is more draining, the physicality of this disease or the emotional toll every loss brings.
I'm not sure I have a point in my post, but more that I empathise with your situation. On a side note, if the doc OKs it for your hubby, I give mine 1 immodium tablet every morning because if I do not, we constantly fight diarrhea. The pulmonologist has assured us that only one is not detrimental, but it really is person specific because constant immodium use can make the bowels "lazy". Not sure what that means, but the doc said just one a day shouldn't do that. So, if the doc says OK, that could decrease clean ups for you.
Big, huge cyber hugs to you, V. You're a gem who is doing an amazing job for your husband.
