"My husband and I had 2 very different experiences.  He didn't chill anything, mixed it, drank it like chugging down a beer, then immediately did the 2 additional 16oz room temp waters.  Said it tasted like cough syrup but it wasn't too bad. It hit 1hr later and an hr after that he was done.  His repeat was exactly the same. His only side effect was hunger. I chilled mine, pinched my nose and drank it all down with a STRAW in about 15mins.  Took a spoonful of honey then let go of my nose. Didn't taste a thing!  I had trouble getting all the water down in an hour, had to switch to Gatorade. I was bloated, a little nauseous, and almost had a headache. Mine also hit an hour later but I went 18 times in 3hrs. 2nd round similar but better."
