Hi Eric, I had the same question. I am also negative and assumed that the medication Lyn mentioned was not an option for me. I had just done some positive reading on it but didn't mention it to my doctors because I figured "What's the point with me being negative and all". Lyn I hope that you can get back to us on this question. If we have a chance, I'd try it. Maybe your doctors know something ours don't. Hope to hear from you soon.
