As I've said before, merely reading the schedule you keep makes me tired and want to rest - and regardless of the mechanical cause of the vertigo (which I agree, especially if it continues, see an MD somehow) I thing slowing down and going a little easier on yourself for a bit might be in order - if nothing else, you've had the death of a close friend, an infection, and a very busy...several weeks? - so it truly may be a sign of your body being a bit over-taxed and needing a slower pace for a while. Besides, it's going to be time for the first outdoor Spring plantings and preps in a few weeks, and if I know you, you'll be wanting to be at top form for that!

I took a spill (tripped over a dead-fallen, barnacle-covered tree) on a trip to a state park on the James in October. Besides scraping up my leg on the barnacles and wounding my pride a bit, I found out later that I'd wrenched my neck when I faceplanted in the sand - I started getting a very odd vertigo that only hits me when I'm horizontal, usually at night. It's a little better now - I figured out that one of my meds aggravated it & shifted it to take it earlier in the day. But I still have nights where every little move in bed gives me that lurching feeling - it can be rather disconcerting, even when you know the cause. I hope yours resolves quickly & you're feeling much better soon! *hugs*
