I agree with taking minerals, however, not just magnesium and potassium. There are 60 minerals and they all work in a synergistic manner, so you need them all. Then all the vitamins, amino acids, and fatty acids.
I would also suggest you take a multi-strain, 50 billion culture probiotic daily... forever. That will help kill the candida fungi in the gut, which will then improve your immune system, which will boost your energy level and well being. This is very important because good health begins in the gut.
I would suggest a product such as:

I would also suggest no more well water, unless filtered through a reverse osmosis membrane, for that is what caused your health issues in the first place.
Do some research on colloidal silver.
