Sorry, I know this is years later but I thought I would answer anyway. Magnesium Glycinate helps with sleep and to be taken at night. For energy try Magnesium Malate. It is best taken before workout.

My daughters use a liquid one made from magnesium chloride, which is intended to be taken by mouth. It comes with a screw on cap and we replace that with a dropper for ease of use. They find it helps to begin taking it several days ahead of the monthly event to reduce cramping.

After researching how to eleavate the pain of cramps, I came across Magnesium. I have only used it when I have my cramps, (Magnesium 250mg) (nothing fancy, i think my bottle cost less than $5)
When I have my cramps, I take 1 or 2 a day, and it really helps with the cramping ( i think magnisum slows the muscle constractions that cause pain).. Im not sure how exactly it works, but it helps with cramps.
