Thank you all for your responses.....
I didn't eat any thing bad, nor did I have any ear infection or headache.
Nothing was on in the rig....it just rocked a LOT when we moved around. But there was that smell like formaldahyde, though it's 11 years old...that may also have affected me. All good thoughts!
I do agree that it must be what trop-a-cal said....
But I am glad to know that it's not normal in these size rigs, and that it's something that we can take care of.
Thanks again for all your help! If we get it, I'm sure we'll be asking more questions in the near future. :)
