Yep, same here, although I don't have straight up insomnia, I don't just wake up and not be able to sleep but I keep catching bugs. Had a chest and throat infection for three weeks and now got a rotton cold from OH but it always goes straight to my chest because of my asthma and I just can't breathe when I lay down.
I also keep waking up either freezing cold or sweating, at least three times last night that happened. I would definitely much rather be up with my newborn than just being up randomly, I hope it isn't like this til he comes.
