Is it common to retain a lot of body fluid when you are on insulin. What is the best way to lose the fluid.?

I'm guessing better circulation and blood control, does anyone else know of anything else I could be doing to get rid of it, Is it okay to drink excessive amounts of water at one sitting or drink plenty of sports drinks? Sometimes I will try to drink excessive amounts of homemad chicken broth, not sure how much salt i should be adding if any, well thanks for any advice. Curious to know if there are any books out there on keeping oneself properly hydrated, will have to look into it unless anyone has any suggestions, thaniks/.
