Hi, my 15-year-old daughter has CFS, and her main problem seems to be the low blood volume, which causes low BP etc. I asked my doctor to start her on Florinef, but it really isn't a long-term solution. And our CFS expert says you have to increase sodium in the diet otherwise the Florinef is wasted. So my question to you who have gone before (so to speak!) is "what amount of electrolytes do you take each day, that you have found to make you feel better long term?". I'm not after what you have used when you've had a bad day, but rather what you take every day to sustain you and keep your BP up. We are currently using Elete electrolytes as we are adding it to home made fruit/vege juices, and I don't think she needs any more sugar than what is naturally occurring in the fruit and veges. You add 1/2 teaspoon Elete to 32 oz (1 litre) of liquid, and that gives you 125mg of sodium and 130mg of potassium. Which is only 5% of the daily allowance for a normal healthy person. Assuming she can drink 2 litres of liquid a day, that means she'd only get 10% of her daily allowance. So how do you get that extra salt into your body? Do you ignore the recommended level of electrolytes per litre of fluid and up it to something higher? If so, how high? She will be getting some salt and potassium from the rest of her diet, but that would take some calculating to work out, and will of course differ each day. Thanks in advance for your help.
