Yes, the SWF (Salt-Water-Flush) does commonly institude an involuntary urge to yak...just like Tequila. Here's what I do and it makes it sooooo much easier: slice one of your lemons in half and have it handy. After every chug of SWF (Salt-Water-Flush) (as much as you can), immediately take a BIG LICK of that lemon. It erases the salty taste and gets rid of the instant urge to ralph. My tummy may still be a little unsettled still but not badly and I don't have to worry about spewing.
(and yes, this post was a way for me to use as many "vomit" synonyms as I could!!! ;-) )
