constipation
"I've taken Dulcolax before and it worked great.  I have a drawer of constipation pills cuz I always need something.  Yesterday at 4pm I couldn't poop & this has been going on for almost a week.  So I reached in my drawer & pulled out the Dulcolax & took 2 pills. Nothing happened until I woke up at 2:45am with severe heartburn & back pain. I thought I might throw up; it didn't  occur to me  the medicine could have caused this until my tummy started rumbling. I went to the bathroom a few times but only gas.  Finally I was able to go & had runny diarrhea for half hour straight. Every time I try to lay down to fall back asleep my stomach hurts again. It's now 4:30am & I'm still awake :("
