Actually, you don't have to go to Tijuana. There is a website that sells the worms. I had an email discussion with the owner of the "worm company" several years ago, when I was desperate. He was going to give me a 10% discount as I was the first MG patient who approached him about it, and in exchange he wanted me to do video testimonials for him to present at conferences. Still, the cost was over $4,000 and I in no way was interested in doing the video, so I passed, although I think it's worth a try for SOMEONE to try it (probably someone with a lot more pocket change than I!)
