An allergic condition seems like a metabolic acidosis had to be looked at first. A preferred remedy is a carbicarb plus potassium and ocassional hydrogen peroxide to kill the Epstein Barr virus that caused the weakness.

The carbicarb plus potassium - to help sleep is:

1/8 teaspoon sodium carbonate (washing soda) plus 1/8 teaspoon of sodium bicarbonate plus 1/8 teaspoon of potassium bicarbonate (or tripotassium citrate) in 1/2 to 1 glass of water taken 2 or 3 times a day. It seems to work best in helping sleep such as Astenia (a combination of CFS and insomnia) so is preferably taken 2 hours before sleep.

A borax may drive out or chelate the fluoride and often does reduce the fluoride and help some of the condition. the dose is often 1/8 teaspoon to 1/4 teaspoon borax in one liter of drinking water often taken 4 or 5 days out of a week. In a few cases bought on by Morgellons, but often do have the assoicated insomnia and CFS, vitamin B complex taken once or twice a day in the form of B50 were helpful. However, 5-10 drops of food grade 3% H2O2 mixed with the mentioned alkaline drinks of carbicarb + potassium were fond to be most helpul in boosting the energy levels for about 3 hours, maximum, so it's taken 3 to 4 times a day, which equals 9 to 12 hour workday. While alkaline is essential as well as vitamin B complex also, H2O2, magnesium and malic acid are also important against the CFS, but not for insomnia - that's taken care with the carbicarb + potassium, the magnesium dose requires larger then usual dose as in 1000 mg of magnsium chloride, but this dose can be lessened to 250 mg x 4 plus 250 mg of malic acid x 4 also. To neutralize the acidic malic acid, some baking soda of similar amount can be mixed in a glass of water or 1/2 glass of water to neutralize the acid. These are the ones I believed did cure a couple of cases of insomnia and CFS.
