It’s that nasty tasting huh? I am a “super taster” sadly, so lots of the formulas taste that way to me, but I just put them in water and chug it, then wash it down with more water as fast as I can! I tell myself – “it’s medicine, not candy – suck it up buttercup”! I can’t tell you how long it takes to work since I haven’t made this one yet, it’s on the list of those to make though. I have found that it helps (for me anyway) to use really cold water, not room temp. Hopefully that will help someone else.
