I try not to drink much from dinner time onwards so as to minimise trips to the loo in the night. I do drink about 6 glasses of water during the day & 2 or 3 coffees in the morning. But l still get up in the night 3 to 4 times. Just a symptom of getting older?
No, I'm not diabetic Jack. I learned the hard way that if I get dehydrated, I get very bad headaches & have had the odd migraine too. Hence the drinking of lots of water throughout the day.
If you still feel dehydrated when drinking loads it may be your body isn't using the fluid effectively.
You could try an EPA supplement. An osteopath recommended it to me to keep my joints hydrated esp when I mentioned I felt dehydrated even though i drink loads.
I had the same problem and my doctor told me to drink Cranberry Juice. I get the Ocean Spray, plain Cranberry. You might find it a bit unusual to start with but it is quite sweet and not too strong, two or three times a day should be fine. Apparently it clears out any urinary tract infection and does seem to help. Natural too !
