Hello @cvg50

Please forgive me for interrupting a discussion you have been having with @astaingegerdm, but I wanted to weigh in on this question. I also suffer from something called "slow transit constipation" most likely due to several surgeries of the upper digestive tract. The most important thing about using Miralax is consistency. For me, it needs to be used daily. I generally mix it in my morning coffee or other hot beverages.

Sometimes when Miralax alone is not working I'll add an extra dose in cold water and also add some Metamucil. This type of combined cocktail generally helps.

Just some ideas for you.
