Question for DSrs

Good. This is definitely a better safe than sorry thing.

I thought the EXACT same thing.  Why on earth wouldn't they call 911?  Something to hide, maybe?  Very curious....

 
There is another DSer who said that she only drinks with medical personnel because she has passed out before.  I can't remember who it was, but she's a relative newbie (less than 18 months out, close to my date, I think).  Maybe she will chime in.

My first response is that those neighbors are NOT your friends, and God only knows what was in that glass.  I'm glad you're feeling better, and I hope the tests get to the bottom of it.
