I'm in love with the LL Magenetic Clay baths. I haven't yet been able to quit smoking so I use them quite a bit (usually once a week) to help with my toxic load while I'm getting my head right to quit. I alternate between the Smokers and the General Dtox (cannot remember the name right off hand), but the smokers bath is my favorite. I only use one cup per bath and it works great. For some reason (probably circulation and reduction in toxic load) it also helps my lungs and FM symptoms, especially pain in the shoulders and neck. You can pick up the baths for $39 on their ebay store.
or at the main site.
Mixing and cleanup - I don't follow their directions cause my method is much more simple. Put about an inch
of straight hot water in the bottom of the bath and sprinkle 1 cup of bath clay over the entire surface. Go slow or it will clump!! Wait 15 minutes and take a wire whip after the entire bath for a minute or two. Fill the rest of your tub to a comfortable level (I like mine real hot). If you take very hot baths take it easy on your time or you will get a monster detox headache!! At least at first! If you are using only a cup of clay you can simply run it down the drain (followed by a ton of water - you really don't want this stuff to set up in your pipes) I usually let out the water and rinse out the tub then take a quick warm shower to make sure it makes it out of the pipes. If your on a septic system you should probably let it set for a little bit, drain the water and wipe most of the clay out with a newspaper as I cannot see it being to good on the septic tank!)
Hope this helps,
