Three days...question re bowel prep

I have to drink the 8oz of mag citrate ..so will this give me awful cramping or just lots of "going" Its Lemony woooooooo IM sure that will help alot! LOL TIA!!

I bought the mag citrate in cherry flavor at CVS. I drank it at noon the day before the surgery. There was no cramping. Within an hour or two, the trips to the potty began. About every 30 minutes or so and then slower as the night wore on. By the a.m. it was just clear liquid. I never had any cramps. Are you on clear fluids, as well. I was on clear fluids for 5 days before the surgery. That helped! ShelleyAnne
