Welcome to NeuroTalk:
Without knowing more about him, his age, diet and habits, health, other medical data like drugs used, both RX and OTC, etc, it is hard to respond to your post.
We have a busy PN forum here where you can read information on the subforum and post on the regular part.

Some people get really low in magnesium because American diets are poor in providing it.
A simple epsom salt soak for the feet before bed may help. Magnesium will go thru the skin that way. 6-8oz in a bathtub or 3 oz or so in a dishpan sized pan, and lukewarm water for about 1/2 an hour or so may help.
