No, it's not that I have suddenly started sleeping through the night. But I may have found a solution to the heavy body aches I have every time I wake up (each time I get up to go to the bathroom during the night and in the morning when I finally drag myself out of bed for real). Here is what I've been doing so far that hasn't worked: sleeping on my left side (the entire web assures me that this is best for me and the baby because lying on your back or right side reduces blood flow to the heart), putting a little pillow under my belly in case its weight is pulling on my back, putting a pillow between my legs to support my hips, and putting a second pillow under my head.
Last night I got rid of the pillows between my legs and under my belly, and I didn't worry about staying on my left side all night. I kept a second pillow under my head, but the top pillow I laid perpendicular to the bottom one so that if I was lying on my back I was on a slight slope and if I was lying on my side I could put an arm under it and hug it so that I'd be more supported. I woke up once (or twice maybe?) to go to the bathroom and had almost no body aches, and this morning I feel fine. Yay! My theory is that it's the slope that helped my blood flow.
Of course, there's another possibility, which is that heat is my problem. As of yesterday (just as temperatures dipped below freezing in Philadelphia), our heat stopped working so it's been really cold in here. So although our poor guests from Florida are freezing and walking around with their coats and gloves on in our apartment, maybe the colder air was good for my sleeping. But hopefully our heat will get fixed today (please, please I hope that maintenance isn't off on MLK Day!), and so I'll get a chance to test these two possibilities. Either way, it was nice to wake up feeling almost normal!
