I definitely need something to help retain fluids. I have adrenaline all the time so it goes straight through me. Florinef helped at first but I started having adverse side effects. I take about 6 salt tablets a day, doesn't really help. I have very bad IC and recently went to shands medical center. They did a battery of tests with catheters and it showed that soon after I'd empty my bladder there'd me a lot more urine in it. Lithium seemed to help for a few months then stopped. Also, I can't seem to find a good electrolyte drink that doesn't have citric acid or all the sugar calories. Thanks.
