I have an appointment tomorrow early morning at the Saturday urgent clinic at my doctor's office because I was drinking Gatorade and 4 hours later used the bathroom and it was all pure liquid. The nurse said the miralax doesn't stop working immediately after stopping it! I only stopped it yesterday. I've had diarrhea for 6 days and been taking the miralax for months! My primary doctor said to take it once a day so I did. I have been drinking Gatorade but the nurse said to drink it half strength with water. My tongue/mouth is so dry it hurts to eat solid food. Drinking diluted Gatorade now and lying in bed.
