hour before or after drinking the MiraLAX®, they will not be absorbed.
ξ 9am or earlier: Take 4 bisacodyl tablets with water. Do not chew or crush. Do not
take within 1 hour of taking an antacid or other morning pills.

the powder dissolves. Refrigerate.
ξ 12 noon: Start to drink the MiraLAX® mixture. Drink one glass every 10-15 minutes.
Drink it quickly, rather than sipping small amounts. This will help the bowel to empty.
Finish this mixture within 2 hours.

steady stomach pain, get light-headed and dizzy, don’t have any bowel movements at all or can’t
