I took too much miralax (polyethylene glycol) now i have been on the toilet for 6 hrs it started as a solid now is a grity water substance... what is wrong?

New diet and wait!: Miralax (polyethylene glycol) is an osmotic laxative, which means it draws water into the gut to soften stool to aid in producing a bowel movement. Try a BRAT diet (bananas, rice, applesauce, toast) to help reform stools and reduce diarrhea. Symptoms should begin to resolve with this. Consider adding OTC Imodium, this time according to the label directions:) Drink water to replace the fluids you have lost. Take Care

Miralax (polyethylene glycol) OD: Mirialx is an cathartic laxative. Make sure you are hydrated as dehydration is an effect and can be debilitating Drink 2-3 liters of water alternating with juices, Gatorade to avoid losing electrolytes. Avoid milk products with diarrhea . If does not resolve today seek medical attention, if bleeding seek attention immediately. Please take medications as directed, OD can cause serious effects.
