Had two near-migraines in the past week.  This means migraines that are noticed early, when I take drugs and go to sleep and they go away, leaving me only a little fragile afterward.  There may be some hormonal implications there, although I think copious amounts of cream in last night's dessert, along with (for me) copious amounts of red wine and staying up till midnight because I was drinking said wine in a very comfy armchair and no-one required me to talk to them, so I kept thinking "I'm tired, I think I'll go to bed" but continued sitting there... I think all of those played their part too.

So it seems I can have up to 3 triggers, and get away with it (provided I'm not overtired or stressed) but 4 or more is a bridge too far.

Haven't had a massive migraine for a fortnight, and my neck was out of whack then, which was the trigger.  Mind you, that one was truly horrible.  Just to remind me, apparently.
