helps keep you hydrated, helps cleanse the system, want to help any way you can to get the nicotine and cotinine (what nic breaksdown in your system to). cotinine can stay in your system for up to 3 wks from last use. the faster you get everything out of your system the better off you are from the physical craves. the psychological craves is a different story. and in general the better hydrated you are the less craves for anything, be it dip or feeling hungry.
