Many thanks all -- third day and still feeling better -- despite period cramps!
Woke in the night with an awful sweat BUT I usually have trouble first thing, about 6.30, before I get up. OH notices because I throw the covers off... This morning he suddenly said, 'you haven't thrown the covers off!'. Yay! Could be fluke, of course, and I'm not counting chickens

-- but it's nice to think that things may be on the move. Today already I still have a lightness... unusual. Normally third day of period and I'm dragging my knuckles... But it's an internal, basic lightness. Maybe it's as simple as that I feel hopeful.
Whatever the case, I'm enjoying it as suggested, and trying to get some good work done while I can focus. Cheers all!
