I use a High 5 tab to flavour; you need something with the malto/fructose mix as it tastes of nothing.
You are likely to have finished the session before anything hits your blood stream anyhoo but the carb mouthwash effect might help a bit. AIS just use boiled sweets to do same thing.

by some maltodextrin and some fructose
Mix to your taste. Fructose is sweet, malto not. I normally go 4:1 M:F.
