*sight* You've taken 7,200mg of guaifenesin. You are most likely going to vomit profusely and have a terrible time. You were warned.
Not necessarily, I've taken that much and been fine, I've also puked off of less though.
Yeah, like I said, "most likely," still though, it's really such a pointless thing to do when it's easy to just get syrup that only contains DXM.
