Dehydration and cfs

After yesterdays post I left this response on the bury/ bolton support group message board :

It has made me wonder though - i thought the dehydration thing was a symptom.. what if it's actually a contributing factor?
I was just talking to stef about it and he says i'm actually better when i'm drinking loads - I know when I was in Italy I handled everything fine - and we walked for MILES over there! but I was drinking water practically constantly all day every day because of the heat.

I know I was amazed at how well I coped, but I did have a mini relapse when I got back - but by then I'd gone back to my normal 'drink when I notice i'm thristy' routine - which is definitely nowhere near the rda..
It's just, ever since I first got this thing I'm always thirsty - so much so it becomes a background thing that you ignore until you can't anymore - and my lips are constantly dry and flaking, i get mouth ulcers all the time and.. well i'm just dry and run down even without the cfs stuff.

and Louise swiftly responded thusly:

There could be something in what you say as Dr David Bell, chair of the CFS advisory committee in the US, says you can reverse the symptoms of ME, but it only lasts 6 weeks, by giving an ME sufferer saline infusions. Also, there is research saying people with ME have low blood volume and water and salt increase blood volume. Drinking enough water is definitely essential for people with ME considering the research that points that way.

Which then made me want to know more.
This article gives quite a thorough accounting of the ways in which dehydration could be responsible for many of the symptoms of cfs - and I have to agree with it because those symptoms lessoned when I was in Italy and drinking more than my body weight in water - I had no aches and I didn't suffer any more than the people I was with after all that walking.

Now, the website of Dr David s Bell gives an account of the saline infusions Louise mentioned, I know when I was in hospital and they had me on a drip that was simply saline, I felt 'fresher' my lips plumped out a bit and lost the dry flakiness that I always seem to have these days - my eyes also lost the 'gumminess' I always have, even when they're not dry they feel 'tacky' as though they're drying out..

Still, it's unlikely we'll be offered anything like a weekly/ daily saline infusion in the uk so it's pointless going down this road. But I'm still going to try and up my water intake (she says.. )

I've just realised i've not had a drink yet today and it's already 1.20pm I need to set up a reminder system on my phone, if I drink a pint every hour it'll be approaching my italy intake and that's one way of determining the difference.
