I take these baths every now and then. I usually do see a small drop in my weight, but nothing amazing, usually not a pound. I use one cup of the salt, and one cup of the baking soda and get the water so hot I almost can't get in. Then I sweat like crazy! Which I think is the point of the bath. I usually feel very weak afterwards so just sit around until I feel better. I wonder what would happen if I used less salt...?
