I hear your frustration and underlying fear that you aren't doing enough. You are. The old adage "you can take a horse to water, but you can't make him drink" can be applied here. Hydration is so important; lack of it leads to UTI's. My husband suffers from ALZ is now in a Memory Care Facility. I visit daily and bring him a container of ice water with a straw and a small bag of potato chips. The chips make him thirsty, so he'll drink his water. Is it enough for the day? No. But it makes me feel like I've had a small win. He had a fall, broke his hip, and had to be in rehab. All of these setbacks caused him to lose more and more weight. With ALZ, his essence is long gone, but now I see him physically shrinking before my eyes. Think about tiny snacks like you would have for children. For example, cut a banana horizontally in half and slather with peanut butter. Put the halves back together and cut it into chunks. Freeze them to pop out for a snack. Little portions often work better. Vent away. It is essential for your mental health. I vented and shared on this forum for many months when I was caretaking for my husband at home. Reach out to those who have walked your walk. You are treading water and need a lifeline.
