That's a lot of magnesium, maybe split the pill in half.maybe once or twice a week at night. or speak to your specialist about the amount(Mg's) for you.
I take Magnesium Oxide,420 mg, twice a week at night, can be hard on the kidney's, so drink lot's of water with it. It not only keep's me regular but it's known for it's calming ability.
Plus I just started up again with my Restoralax (Canadian version of Movical and Mira lax). Since I've started up again, gonna take it with my breakfast, maybe twice a week.
Start gradually ,until you find the perfect fit..:)
