I passed the 3 year mark on 1st April. Yesterday I experienced my very first “window”. All my symptoms lifted and I felt “normal”, even well, dare I say it. I went out for a walk and it was fine. Although I started walking last year, it is completely different now. No effort, no concentration required, no heavy legs. Today I am back in bed but my symptoms have eased significantly. I am very hopeful and very heartened.
