when do I take the Milk of Magnesia?

I'm having surgery on Monday at 6:30 am and cant remember when I'm supposed to take the Milk of Magnesia? can anyone help? thanksss

Good Luck on Monday!!!! Every Dr is different I had surgery last Wed and never took Milk of Magnesia. Even if someone else takes it they might do so on the same schedule as your Dr... Read all your paperwork and call your Dr to get it right!!! good luck Ann

My papers say at approximately 1PM the day before. Good luck!! My surgery is on the 22nd.. Best Wishes, Michelle
