Crabby- it's not a physical problem with drinking, it's that I don't feel thirst. If left to my own devices I can go all day and suddenly realise I haven't had anything to drink (at all) for 10-12 hours. As a result, when I do drink, even just a 250ml glass in one go, I feel way too full, I get reflux of the fluid (yes even water) and I go to the toilet. A lot. I do keep dioralyte on hand for dehydration. The sports drink was just because I was out shopping, had fatigue come over me, and wanted something to pick me up a bit so I could get home.
I checked the back of my hand, and it pings back pretty darn quick (too quick to see it), I had 2 litres of water (plus coffee and juice) yesterday and have about 250ml to go to 2 litres today. And my fingers are still wrinkly. So I don't think dehydration is the problem.
As for hand cream I use whatever's at hand, body lotion, aqueous cream, hand lotion, anything moisturising really. I have got some proper Dove hand lotion somewhere, I'll see if I can dig it out and just use that for a bit.
Glum chump- thanks for the idea about anaemia, I have been in the past (only came off iron a few weeks ago) so will ask my GP to check.
