I'm wondering if some you have had fluctuating blood pressure due to the PD or its meds. My doctor is speculating that some of my low energy problem could be related to low blood pressure, and is recommending salt tablets. I can't find these, but am filling capsules with table salt. Can someone, perhaps our nutritionist Katherine, tell me, in terms of fractions of a teaspoon, what the recommended intake of salt per day is, and what would be a toxic level? M.Dawn 55/6
