Echoes of the past....trimesters that is...

I have never re-experienced things in my last trimester that I did in the first...except for fatigue...but I have really been noticing things like my sense of smell being much more sensitive, nauseous feelings because of certain smells, etc....weird, huh? And unfortunately, not many other things than eating out sounds good to me these days...just like at the beginning when those awful nauseous feelings only permitted random chicken caesar salads and lots of hamburgers...it is only unfortunate because our money tree is really short and not very leafy these days!! :) Has anyone ever experienced this before??
