pb50 -- I am glad that you are doing everything in your power to better your health. You have endured much with all of the shots and boosters while yet being smart enough to know the time frame that you need to pause them. You and all of the others who have helped me with information and knowledge are a true blessing. I hate that each of you are going through so much and hope that everyone gets some relief at some point soon. Thank you for sharing with me.
