Having a Sigmoidoscopy tomorrow. Prep instructions from my doctor say to drink 10 oz of magnesium citrate at 4PM and then one enema before bed and one in the morning.
I drank the magnesium citrate 4 hours ago and I have yet to have a bowel movement. Is this normal? When I prepped for my colonoscopy I was well into the evacuation at this point in the night so I'm contemplating a call to the on-call physician.
