Wow! Sounds like you are doing right. Might see a doctor about it. In a blood test they might find you are low on something like iron.

I was just reading that low magnesium can causes some of this stuff. Try taking Vitamin D3, vitamin B12, and a really GOOD mineral supplement religiously, and give it time to work.

Make sure you are not anemic. Try ferrous sulfate daily. Also completely rest one day a week, do nothing at all except rest. You won't be tired then. It is one of Gods commandment in the Bible. Work 6 days and then rest.
