Hey!
The pico silax is pretty gross stuff. If you can find it, try to get it in cranberry flavour, the orange is not as good. I am pretty sure they want you to mix it with water. You can always chase it down with something else.
My trick has been to mix it, then suck it back through a straw as fast as I can to bypass my tastebuds and get it over with.
Not fun, but not the worst thing ever. Good luck!
