You reminded me that the average population has absolutely no idea what they're doing, therefore I can't trust them with a simple prank.  There are too many people that are either too stupid or too lazy to follow instructions, so I pulled the post to prevent some retard from doing it wrong.  Most people wouldn't bother to read the damn labels even if I did explain it to them. You clearly don't know much about pharmacokinetics or pharmacodynamics.  (No, they are not the same thing.)  There are a lot of different types of laxatives.  Each class has different mechanisms of action.  Drug interactions are exceedingly rare, and even then still irrelevant since they require 1-2 WEEKS of continuous concomitant use of both agents before an interaction might be seen, and even then it's still a relatively minor problem. There are six different classes of over-the-counter laxatives.  Bulk forming, hyperosmotic, stimulant, saline, emollient and lubricant.  Don't make blanket comments like that until you can accurately describe the difference between methylcellulose, calcium polycarbophil, psyllium, polyethylene glycol, glycerin, bisacodyl, sennosides, docusate sodium, docusate calcium, magnesium citrate, magnesium hydroxide, monobasic sodium phosphate, and dibasic sodium phosphate.  And I want the explanation at a molecular level, the same way I learned it. As far as fatal?  Not a fucking chance.  I'd tell you to take a pharmaceutics class, but I guarantee you'd fail.
