What happens when you take a massive dose of Ex-Lax?

Recently my friend Jeff was on the third day of being unable to make a bowel movement. He was extremely constipated, having ingested massive quantities of McVitie's Milk Chocolate and Caramel Digestive Cookies (something about eating cookies from the UK is enthralling to Jeff). He did not realize why they call them "digestives," until he went the next three days without a movement of the bowels.

Desperate for relief, he decided it was time to call upon Dr. Ex-Lax. As we drove home from our embarrassing trip to Wal-Mart, I opened the package of the famous Make-You-Poopalot medicine. And thus begins the saga of Ex-Lax Extreme, or The Ultimate Colon Cleanse.

Skeeter: "What is the suggested dose? You always need to take a little more than they say."

Jeff: "Ummmm ... the box says take one or two daily."

Jeff pulls the chocolate bar out of the packaging, and sees an outline of four pieces.

Skeeter: "Well, take four. Just take the whole bar."

Jeff: "Okay."

Jeff unwraps the delicious-smelling chocolate and consumes the entire bar.

Skeeter: "So how many was that?"

Jeff counts the remaining bar, talking with a full mouth.

Jeff: "Ummm ... twelve."

Skeeter: "Dude, holy shit! That is like six times the suggested amount!"

Jeff: "Is that bad?"

Skeeter: "Yeah dude! You're supposed to take that much in six days!"

Jeff: "You told me to eat the whole bar!"

Skeeter: "I didn't know it had twelve pieces in it!"

Jeff: "So? You still told me to eat the whole bar!"

I knew Jeff was in for trouble, but I didn't know how much. I'll let him tell you in his own words.
