This Is MS Multiple Sclerosis Community: Knowledge & Support

It's interesting, I was always drinking, water or diet coke being my beverages of choice. It's early days still but I think that need to always be sipping is gone. Overloading the system with fluids to increase the vasculature might well have been what I was doing.

Electrolytes can be found in foods and fruits. Gatorade is high in sugar concentration and I highly recommend against it as a hydration source.

"The best source of electrolytes is not from drinks, but from food. Fruit and vegetables, even canned or frozen vegetables, such as corn, carrots and green beans, are high in electrolytes, as are bread, milk and fruit. Water with a small pinch of salt, sugar and flour added to it will provide lots of electrolytes for your body. Tap water or spring water does not contain electrolytes."

Especially when sick, one should not drink anything highly concentrated with sugar for replenishing liquids.
My companion makes his own 'gatorade' by taking water, lemon or lime and adding a pinch of salt into it and then a few drops of stevia for sweetness...Tastes just like 'gatorade'...costs less to and is better for you.
