I know that finger test. I felt so ill afterwards!

Sometimes I take 2 paracetamol and go to bed. If in lucky i'll wake up not spinning but it's hit and miss. I don't really find anything helps with the fog., though haven't tried any specific medicine. I like to lie in the bath with candles and classical music, that's about the clearest head I get. But I have to be very careful not to have the water too warm or let it get too steamy otherwise I'll get dizzy all over again

I think that there's something about warmth that helps. It takes my mind off the pain, if i lay down with a hot water bottle. Also, lying on your back with one foot on the groud helps stop the room spin. It's all worth a try !
