I have to be careful with this or I get the poopy doopies!  Lots of people are that way but it's a very important substance so don't neglect it. Not ever. I use Magnesium Asporotate from Solaray and order 250 capsules.  Cheap and does soooo much for your body.  Just get some and take it, but not too much or you'll get the shits.
