I just started taking the magnesium citrate. Each capsule has 500 mg. I took two and I'll take the third later. How soon do you think I'm going to be moving and shaking to the potty? Will it help clean me out?I decided to start taking some digestive enzymes also because my new GI doc thinks that I have delayed gastric emptying, so I'm hoping that this will help move food through faster. Thank god I have nothing planned this weekend.
