Next time you fast make this. I call it Greaterade powder.

1/2 C Celtic Salt

1 3/4 tsp Potassium Chloride (Nu Salt)

1/2 tsp Magnesium Glycinate

Combine all of it an put it into a grinder until it's dust. 1/2 tsp per quart of liquid is all you need. I think you are dehydrated and that's why the headaches. Just water ain't gonna cut it. You NEED the salt on a cellular level to let the water into your cells.

Now, the reason I call it Greaterade is because it makes a great sports drink.

Recipe for 1/2 gallon

1 Cup of fruit juice of your choice. The OG Gatorade was OJ.

1/2 C sugar or honey

1/4 C lemon or lime juice (2-4 lemons or 3-5 limes juiced)

1 tsp Greaterade powder

Remainder of the 1/2 gallon water

Dissolve the powder and the sugar in some of the water over a low heat. Once dissolved add a few ice cubes. You do not want to pour it hot over the lemon/lime juice as it will destroy the enzymes you need for rehydration. If you use honey make sure the water is not hot to dissolve it for the very same reason.

Mix everything together in a pitcher and add water to round out your half gallon.

This recipe is for heavy duty sweating, like at the gym or in the garden. You can cut the sugar and powder in half for every day hydration.
