If you search Life vantage with DR. Joe McCord you will likely be able to find some videos on You tube, also a news cast on prime time ABC news about the products, The down side is you need to sign up to be able to get the products and they are expensive but if you are desperate for something this is worth a try!! Its all natural so it can take up to a year or more until you get better, I saw an awesome difference in 2 weeks! I had a chronic cough all my life and 2 weeks later it was gone! I took it for a year, then I got off for a month, and my cough started returning!! so it does amazing things! since its all natural, no one can predict where you see improvement first? So for GBS I don't know what it will do, but its an awful disease to have, and anything that helps even a little bit, will be worth it! I spent all day with my dad yesterday, I'm so thankful for my brothers and sisters that we can trade off with, It gets awful lonely for both mom and dad while they can only patiently wait for recovery! I appreciate your comments! Thanks!
