Hi Lapis, I just ordered a zapper, which hasn't arrived yet, but one of my biggest problems right now is congested lymph. I have tried a bunch of things, and still feel like it's toxic and stagnant. What have you heard about this unit for working with lymph? Do you know where I can read more? It's something I had not heard of before. I'm doing skin brushing, excercise, herbs (cleavers, right now),lemon-water, lymphatic massage, haven't done the saunas yet, but at some point soon I'll try that. Any suggestions would be much appreciated. Thanks!
