Read various posts on google saying you need to drink so much water a day. One calculator suggests you take your weight in pounds, divide it by 2 and drink that much. e.g. if you weigh 150 lbs, drink 75 fl oz of water daily. That's about 10 cups, 8-10 glasses a day.
Trouble is, I am up seemingly all night [last night every hour, on the hour, apart form one stretch of 2 hours sleep] peeing and I wake up really thirsty. I have tried not drinking after 8pm, but then I go to bed thirsty and wake up even thirstier, sometimes with a headache and nausea.
I am also really struggling with stiff hips and I pull muscles in my hips and legs all the time, sometimes just by rolling over in bed.
I'm also a regular runner but am struggling to keep that up. In the last week I've had a few days off after my back went into spasm on Monday, then I tried a short run on Friday, got cramp in my calf and tore a muscle in my calf [I think - not badly, but enough to stop me running for a while - again].
I daren't drink that much liquid as I'll never sleep again! Any advice please as I'm starting to feel very old now and I'm only 56. Plenty of mileage in this girl yet.
