constipation
"I've used Dulcolax just a couple of times, once when I developed constipation for in excess of a week when I was on an antibiotic for 30 days and once when I was on vacation and traveling by car for over a week.  My experience is much different than most of the folks who have provided reviews here.  In both cases, I used the maximum dose of three tablets, as I am over 6' tall and weigh 200 lbs, plus I was tired of being constipated.  I took them at about 5PM in both cases, and made sure to drink a few glasses of water over the next few hours.  By morning, the constipation was finally relieved in each case, with no real side effects.  No cramping, no discomfort, it worked great for me."
