Maybe you've tried this already, but here's a few things that helped me (day 15 today):
1) in the beginning, I would hold my breath while I drank and just chug down as much as I could until I had to take a breath again. I could usually get it all down in three steps that way, and not be affected by the taste. You can also try holding your nose.
2) now, I find that if I do something else while I'm drinking, like read the forum, and concentrate on the reading as opposed to drinking the swf, I hardly notice what I'm drinking.
3) I also try to concentrate on the warmth of it going down, as opposed to the salty taste.
