It is common for older people to not absorb nutrients or water as well as they did when they were younger. If you read the earlier comments you will find that I am not the only person here like that; which was what I was trying to find out. I was hoping for commiseration, i am comfortable and satisfied with my doctors' diagnoses.
At the age of 61 I went to my doctor recently and told her i was tired of waking up 3 or 4 times a night to pee. She told me, stop getting up. I have learned that i can go back to sleep sometimes and now I don't usually get up to go more than 2 x a night.
I am in really good shape and enjoy good health. The fact is, my body is 61 years old whether I like it or not. We have to deal with the hand we are dealt.
thanks everyone for your thoughts.
