Hi B.,
I'm in my 22nd week of my first pregnancy and I'm very happy in the second trimester. Right around were you are I was almost comatose! I would fall asleep around 7:30 - 8:00 each night. I would try and stay up but there was just now way, I was so tired all the time. I even cried on the way to work a few days because I was just so tired in the mornings. I'm similar in the sense that I am high energy and I am always on the go, so it almost made me feel depressed to be so tired all the time! The best advice I can give is try not to fight it too much and when you can grab a power nap, they helped me stay up all the way until 9:00. Sounds like that might be a little hard with two little boys, but a 30 minute nap did help me out a lot! Also know that around 12 weeks I had a renaissance and felt so much better and had my energy back, so hold on you are almost there.
Good Luck and I will send you extra energy vibes,
-H.
