Thank you all for the encouraging replies. Please keep 'em coming (I get a HUGE amount of reassurance from these replies and it puts my mind at ease!).

I forgot to mention that the stiff neck, throat probs, etc only occur in the mornings and this morning I had a stiff neck but my throat was'nt as bad as previous mornings.

About my friend/roommate - he said he and his friend used to fish by the lake sitting accross each other and bats used to fly between them and swarm over thier heads. Gosh, if that had been me, I think I would freaked out and dove into the lake!. I also read posts on a bat board where people were claiming that they had bats "dive bomb" them. Other people were talking about building "bat houses" to keep the mosquito population under control. I have learned a lot about bats so far (most good but some very frightening).
