Which supplements are you taking? Getting enough magnesium is so important. So is getting enough zinc, iron, copper, selenium, iodine, and chromium. is your diet good? Have you checked to see if you are hypothyroid? Aside from blood tests, you could check your temperature when you first wake up and see if it is too low. if if is 36.5 C or lower, that might be one indication of hypothyroid. my temperature in the morning was below 36 C until I started taking plenty of iodine. Now my temperature is much closer to normal. While it is normal for your temperature to be a bit lower in the morning, if it is is too low it can make you feel horrible and zap your energy. Exercise will help raise your body temperature. Many of us have great muscle ache and fatigue, so the only exercise we can do is perhaps a few blocks of slow walking, and even then just when we are feeling a bit better.

Some supplements to help boost energy are carnitine and C0Q10. I am taking 1,000 mg a day of carnitine, and 100 mg a day of CoQ10.

This article outlines what you may be deficient in and what supplements might help.
