When you're getting killing all that stuff, your body is freed up to function and will look to start functioning to heal and repair. And it'll reach for vitamins and minerals all over your body. Make sure you are taking alot of supplements.
I take the SomaLife LifePak

as well as a calcium/magnesium supplement you can get from your local health food store. magnesium will help your body with the constipation. start with 1000 mg and adjust accordingly.
Also, drink alot of water throughout the day, like almost a gallon.
