...how did you make it through the last few weeks of pregnancy?

I've been going to the chiropractor for months now (heck, he helped get my body back into whack so we could get prgenant)... and now I've been going once a month for the second tri. Yesterday, while I was at my appointment, we were talking about the third tri and the changes my body will go through and he told me I'll have to put my feet up throughout the day. IMPOSSIBLE. I'm a nurse... I work 12s... always on the go (especially in the fall/winter) and I will NOT be able to do that. He told me he'd write me off for the last 2 weeks.

What'd you do if putting your feet up/sitting was impossible towards the end?
