Hey Jen - the pharmacist might also be able to advise you...
as far as the water pill, the safey concern is that you aren't getting fluids, regardless if the reason is physical or psychological. so for lack of a doctor, ask the pharmacist, is the water pill safe with your limited fluid intake?
it ticks me off that the clinic that didn't call you back!

that is good that you were trying to take sips... do what you can. and i am glad the nausea has improved. i hate nausea.
