ok here's what you do:
*get some lemon diet coke (it absolutely, positively HAS to be lemon diet coke--- no EXCEPTIONS)
*place exactly 1 gram (or whatever amount) on a piece of paper or soda cap.
*take a small sip of the diet coke.
*QUICKLY take the shot of B5 (make sure the B5 is on top of the diet coke you already have in your mouth)
*swallow quickly.
*If all goes well, you should have not tasted the B5 at all since when you downed it, the diet coke wetted the outter layers of B5 creating a casing (sort of bolus) in your mouth.
*practive practice and more PRACTICE... you'll be on your way to tasting nothing..
