i too CAN NOT drink the salt water, it literally makes me vomit every time. i've given up trying to do it. i just drink lax. tea the night before and in the morning, much more soothing for me. i feel it probably doesn't work as well or as thoroughly as the SWF, but hey, it's something. i also do enemas while doing the Master-Cleanse to keep things moving outta there if the tea isn't effective enough.
good luck. i'm about to start one again, it's been almost 2 years!
