I HATE constipation. It rules my life.
Miralax does work.
extra fiber does help.
Aloe juice is good
If its been longer than 3 days, you may need some help to get it out of there. I find that sometimes its not the fact that poop is there, its the fact that i CANT push to make it get out!

Its like I have no co ordination with what my bottom is supposed to do normally!
Hang in there.
