I Had Been Becoming Dehydrated. I Generally Don't Drink A

I had been becoming dehydrated. I generally don't drink a lot of fluids during the day. The last two weeks I've loaded up on liquids. Now I have a constipation problem. I don't care much for plain water, so I've loaded up on orange juice, V-8 juice and plain old vitamin D chocolate milk. I don't care for skim or 1% low fat. Which
is giving me the issue.
