Bockage
Blockage? If you ever have a blockage which you probley will sometime, try drinking some Coke from a can or bottle not fountain pop. If Coke can take the rust off a bumper it surly can eat through your blockage. Since you are blocked the Coke will bubble up so drink slow and give it time to work. It may even help you bring the chunk food back up! Do this in the bathroom. I carry some Coke with me all the times. Its my liquid plumber. JUST DON'T ABUSE IT.
