Thanks heaps WTH - I've read that too (and don't worry bout the TMI, I've had the same thing ) and that's what I started thinking.. It's been happening to me for the last week, but only just hit me really badly last night.

I'm feeling a bit better (no thanks to the builders using a bansaw at 8am and waking both myself and DH up after DH didn't go to bed till 4am because of getting work done) but still having the constant nauseous feeling, just not as bad as yesterday
