it's hard to mask the taste/upset stomach. I've been using it to fight off a fungal infection and it has been working slowly but surely. but even thinking about the stuff makes me feel nauseous. i add a lot more water than what i've read and i drink it pretty slowly or else i bring it back up. the thing that i find has helped me the most is holding each gulp in my mouth for about 5 or more seconds before i swallow. i read it somewhere once and didnt try it until much later and oddly enough it seems to help with my stomach at least. good luck to you
oh yeah, and i also keep my nose plugged the entire time to mask the taste because i find it very unpleasant.
