7 weeks. OP is helping in some respects. Took 75% of pain out of crowned tooth giving me trouble past couple yrs. Had neck pain- reduced by 50% and a little more mobility. Hoping that it contributes to system healing but can't discern anything else specific.
You don't have to use the rocks. You can use the hendel regular salt for same purpose. You can do the bottle thru the day but in my I think one shot in the morning on an empty stomach is best.
I have done kefir. Huge die off after few weeks. Kefir has a yeast that goes after candida. Stopped doing it til I recuperated but somehow I think the devils got used to it after I restarted. After a while it became more hassle than it was worth so I stopped. Others swear by its overall health benefit. To each his own. I like sauerkraut.
