Can you eat foods like pudding, yogurt, smoothies and ice cream? They will help with hydration, too. I eat fruits and veggies that help, too, but I am not sure you are at the point of eating those yet.
When you drink fluids you should also eat something that will help bulk. Pretzels are good since they are also salty.
Did your doctor give you Imodium and/or Metamucil instructions?
Are you showing more signs of dehydration?
