I find drinks only temporarily stop drymouth, the best thing to use is something that forces your mouth to salivate like boiled sweets,something sour, chewing gum an all that kinda stuff.

Yeh your first time smoking pot - Have some nice chilled drinks nearby incase of coughing.

And a large supply of chocolate and other great snacky/junk foods, Nowone understands the power of the munchies till theyve been stoned!
