I also take 1500 mgs of magnesium, although I wouldn't suggest that anyone start out taking that amount! You'll not get very far from the bathroom if you do!
Start off with just one tablet on day one, and see how you do. Day two, add another tablet, see how things go, and so on until you reach what is known as 'bowel tolerance'. You'll know when you've reached 'bowel tolerance' because you will either get really gassy or have diarrhea. Once you've reached that level, back down one tablet.
I split my dose up into two separate doses, 750 mgs in the am, and 750 mgs just before bed.

I break up my post because my eyes have been effected by TBI's as well, making long paragraphs very hard to read.
