Binary Choice?

I should possibly consult more if possible with the clinicians concerned, difficult approaching the weekend, but, wonder if I am facing a binary choice? After being told I will receive Ocrevus in Leeds in September, I now have an appointment next week @ Barts with Prof Gavin Giovanonni , or one of his team, with whom I have been corresponding RE Cladribine. I cant have both so is it now a binary choice? My condition is active and my physical capabilities are failing very quickly. Anything would be welcome now.
