Here's the recipe:
1 quart water
1/2 tsp. baking soda
1/2 tsp. table salt
3 to 4 tbsp. sugar
1/4 tsp. salt substitute
Mix well and flavor with lemon juice or citric acid.
Don't laugh but one thing I keep well stocked is toilet paper and at least 1 large pack of the really soft stuff. You do NOT want to be running out of TP in the middle of the stomach flu! I usually buy the cheap stuff but when you've ran to the bathroom for the 30th time that day your poor bottom side really needs the soft stuff by then.
Another thing I stock up on is real Sudafed, not that new PE stuff they came out with. Between Sudafed and Tylenol/Motrin we get through most things just fine.
I usually have several meals in the freezer as well and think I will freeze up some chicken soup as well.
