Vertigo?

So -- anyone in my readership suffer from, or know someone who suffers from, vertigo? I had what I can only describe as an 'episode' last night before going to sleep. I felt fine all day and evening...then in bed, before I'd even gone to sleep (Chris & I were watching a bit of tv before slumber), the bed suddenly started spinning, and not the kinky kind of spinning, I assure you! I thought that was wierd, and settled into my pillow to sleep it off. I fell asleep easily enough, but then, through the night, as I'm prone to do, I flip and flop and move to the other side and each time I recall that the bed was still spinning. I get up when the alarm clock rings...walking sideways to the bathroom...head still spinning. I shower. The motion of me lowering my head to rinse the shampoo nearly makes me vomit. I call my manager, and explain to her that I shall not be into work today and end up horizontal on the couch for the day -- sleeping pretty much the whole morning and afternoon away. I awoke at 4pm, got something to eat. My dizzy head is now more sore than dizzy (unless I put it down), and I ended up going to work for the final 3 hours of my evening shift, because if I didn't, there'd be no coverage and/or someone would have to work extra hours after working the whole day.

You know I'm fairly quick to blame the weather - the high humidity - on my 'afflictions'...and I'm not totally excusing that away yet, for it's a freakingly hot, humid day today. Thank GOD for a/c, is allllllll I can say. And, I write this more to document my story so I can read back and say, yes, every year this time when it's hot, sticky and humid I feel nasty, but the rest of the year, pretty fine. If any of you all have had similar experiences, please feel free to leave a comment on how you handled it or found some relief?
