Answer:
Gatorade Doc told my Mother to drink it because it does have a lot of sodium and also potassium
Decrease your fluid intake - if you have a potassium restriction, this won't hurt as much as gatorade might. Also, see a doctor - sodium of 115 or lower can lead to coma or death.
Eat salty foods - not the best, but it helps; pickles, chips, pre-packaged meals, store bought soups, or just table salt (which you may find tastes absolutely wonderful, but don't overdo it)
