How much salt is it taking for you to get the SWF (Salt-Water-Flush) work. I have tried 2 tsp, and 2.5 tsp. Neither worked. (these were both in 4 cups water). I even tried not going back to bed after I drank it this morning. I did pilates for 45 minutes right after, and still only a small amount of the SWF (Salt-Water-Flush) moved through my system. I would rather do this than the tea twice a day, so could you all let me know what amount of salt to water ratio has worked for you? thanks
