Hello Michel.....I admire you for what you're doing. I'm sure you're inspiring more people than you know. I've done the Salt Water Flush several times in the past. I've had both good and bad results. Probably where you are now in your Fast is an excellent time to Flush. I don't think you're compromising your Water Fast at all by doing a few SWF. But like you said, there may be some Fluid Retention from the salt. At least that was my experience, but then again, I wasn't as 'clean' as you are now. Good Luck....Hang in There.....WY
