At this point in my disease progress I actually find I am much stronger in the evening than in the morning. Perhaps this seems paradoxical. But then I've always been a night owl; I'm rarely in bed before midnight and I've always been a slow starter in the morning. Also, there seem to be subtle psychological factors at work for me; when I wake up, I find myself tentatively testing myself to see if I've "lost" anything from the previous day. Whereas, as I go to bed, I'm finding myself saying a silent prayer of thanks for another day of reasonably good function.
So I guess, YMMV.
