NAC, ALCar and Ascorbic Acid, I mix them all together in a big crystalline heap, take a swig of diet sprite, pour the crystals into the liquid in my mouth, and down it goes! Masks about 90% of the sour tastes when you get the hang of it.
It's easier if the sprite has gone a little flat. The crystals make it fizz up and then it's harder to swallow in one big gulp. Maybe I'll try kool aid in the future.
