@kkathysan Thank you for your reply and all this great information! Unfortunately my brother in law died over 10 years ago in a car accident but he had sprung back somewhat from the Guillain Barre. For some (myself included) EBV really changes or diminishes your immune system. I still feel the effects and have to stay vigilant about what seem to be on going infections and issues. They all started with a very serious case of Mono in my mid 50's. Hugs to you!
