How to survive those last days, any tips?

I'm in my 39th week and I am exhausted. I can't sleep at night, I am uncomfortable in any thinkable position whether I'm sitting, laying down or standing, I have weird urges to smell gas, bleach or basement (don't worry, I am not sniffing any of them) and my appetite is a little low. And besides all that, I am going STIR CRAZY!! How to survive those last few days??
