I just read in another post on here somewhere (I've been reading a lot of 'em so I can't remember who posted) about someone saying they mixed the salt in with the first half quart of water and drank that, followed by the remaining half quart of water with no salt in it. I want to try that myself. I imagine the first half quart will be pretty salty tasting, but at least it's only TWO cups of salt water rather than FOUR.
I noticed that if I mix my SWF (Salt-Water-Flush) with water that is only lukewarm, it is harder for me to swallow. When it's hotter, I find it easier to drink. Not piping hot, but about the same as a cup of chicken broth when it's just gotten cool enough to chug without burning your mouth. (I add the salt to 2 cups of boiled water, stir, and then top it off with 2 more cups of water at room temp.)
