I mixed 17gm of polyethyene glycol with a sports drink! its been over 12 hours and i still have not had the urge to use the toilet! is this normal?

PG: Well, the best way to take it is with water! water is the best thing for helping form a good bowel movement so that it is not hard to pass. It may take 1-4 days for a bm. Take it daily with an 8 oz glass of water. Make sure to make an appointment with your physician if indeed you have had a major weight loss in 4 months if unintentional. You want to make sure your GI tract is ok.
