Miralax...it's basically flavorless so you can mix it in any drink. It's also an osmotic, so it helps bring water into the intestines for softer stools. I have been taking it forever (haha) and it's safe. Buy the generic, it's cheaper. Also, All Bran cereal has 40% fiber daily allowance in 1/2 cup. I often mix it with another cereal and have it every other day or so. Also...warm apple juice. If I am really having a problem, I will heat up apple juice first thing in the morning to drink, sometimes putting miralax in there. Can you tell I have had lots of experience with constipation???? HAHAHA.
