Rrrr: thanks for the great info! glenp: I found something called "popchips" that are baked potato puff things, salty but without the fat. They're expensive for a small quantity though. Kettle bakes might also be good, or asian rice crackers. I as well eat dulse, and vegetable juice, which seem to help me. Overstrssed, Sunday: I agree about the nitrates, as well as MSG. they are completely different from salt and probably harmful. Sensingprogress: I read your blog about the thermotabs. I've had trouble getting them in Canada, so I've been making my own salt capsules, but I think thermotabs could be more pleasant.
