lurking from november since i'm due 11/29

i have been getting out of breath mostly just after breakfast. sitting down is the worst - i think between my baby, my full stomach, and my bad posture there is no room to breathe. so i have to either lie down or walk around. it has gotten easier in the last week though - since 35w or so.
since the beginning of the second tri i've gotten easily winded going up a hill or upstairs. i can walk on level ground for an hour or more no problem, but as soon as i encounter a hill i have to go soooooo slow. and i always take elevators upstairs, but i can happily skip down a bunch of them.
