Thank you so much, Samsara, thank you, Stan - your info has been most helpful. Forgive me I'm answering your post now only. The bad news is that the bee sting created havoc on my CNS - the symptoms got horrifyingly worse, the good news is that the worst is behind me. Today I've entered into a second week after it happened. I hope for it to improve more in the days to come. I also believe (the silver lining of it all) that my post may help those who experience a sudden, totally bizzare worsening of the symptoms even at three or more years off - once you realize that it's just temporary and caused by some external factors, it helps you to accept this situation.
To answer your question - my symptoms at the worst point were; problems with breathing and swallowing, akathisia kicked back (this had been less of a problem before the whole wasp incident), nausea, weakness.
Anyway, I will make it - just a couple of days more. Thank you one more time for your great help!
