Two brands of Sea Salt that people recommend are Redmond Sea Salt and Grey's. People have the least amount of issues swallowing them down. As for water, the Master-Cleanse does not recommend drinking distilled water. You should drink spring water. As for the SWF, I don't recall if it matters. When I did the Master-Cleanse I would buy a case of spring water and use it for everything - drinking in between lemonades, lemonades and SWF. Hope this helps.
