I need to drink more water too

Im trying to follow a low salt diet but the cooks here think by cooking without salt that is all that needs to be done. I wish they would get a nutritionist or dietician in to talk to them about the amount of deli meats and prepared foods they serve...all loaded with sodium, ..and they serve ham and sausage and pork products often..
I've been having trouble with edema and it's not helping my congestive heart failure..
