is wrong, making you feel terrible. She was very ill, always feeling tired etc. When she went to the doctor he told her to drink 2 litres max each day. the problem was that after a few months of drinking more than double this, she was thirsty all the time. So she stuck to the 2 litres of water each day, but had a rehydration sachet every morning and at lunchtime each day too. Maybe you could try the rehydration sachets? Also be careful with what you eat, as salty things make you very thirsty. Hope this helps even a little, and good luck! i am kris, i suffer with fibromaylgia, maybe ask your doctor if you can have tests for that, chronic fatiuge sindrom or ME, they are all realated to each other, just some doctors beleive they are seperate conditions where as some beleive they are all the same. I have suffered with this for 3 years now and i am the same as you, i feel as if i might have a bigger problem like, MS or cancer, its natral when you are just getting worse and worse all the time and nothing can be done about it. I really do feel you might have fibromyaliga tho, i cant get out of bed most days, my whole body feels dehydrated and i als drink alot of water, i get muscle and joint pain, twitches, i dont have control of my limbs all the time, i feel confused....
