We have been rifing for 3 months now, using the FIR Sauna for the same time. I paid $2500 for the GB4000 rife-like machine and $500 for a 2 person sauna that I found on sale on our local Craig's list. I think it is definitely worth the investment. I wanted the GB4000 machine because I can program the frequencies to run multiple sequences back to back, basically I enter what I want it to do and the hit "RUN" and it goes until it has done the series I entered into it.
The three of us have noticed that we have less pain, less brain fog and more energy since we started using it. It is really interesting to notice when we hit a particular frequency we feel an intensification of the symptoms in a particular area of the body. The first time I did it the entire left side of my body went numb and was hard to move. That mirrors symptoms that I have of decreased sensation on that side of my body. My daughter had intense pain in her shoulder, which is one of her particular issues. My son felt like his face was going to to start spasming, that feeling you get right before a muscle spasm hits. It is different for each of us and I think I can say that each of us are seeing improvement. My son wouldn't keep doing it if he felt like it wasn't helping (long story there, let's suffice it to say that he was bit in the head by a tick and a lot of his symptoms have been neurological/psychological), and he has been really good about sticking to his schedule. I have seen a marked improvement in both of them and in myself. My daughter commented that she hasn't seen me "walk that fast in years" the other day when I was trying to get to the car when it was raining!
I have to say that the nutritional guidance from our lyme-literate nutritionist has been a huge help, too. We learned about food allergies and about nutritional deficiencies that we each had and are taking supplementation that is tailored to our particular lab results. I was allergic to three things, my son to one and my daughter to 10! That poor girl has had some major diet changes but since she is feeling so much better she hasn't minded too much.
I hope that is helpful, feel free to ask me any other questions you might like to,
