Pregnancy insomnia? Anyone else have this?

I had the same problem with my second child, I was exhausted too, I would lay on the floor by my daughter's crib, and could sleep thru the day and as soon as night hit, boom, I was awake, it passed when I hit 22 weeks, I tried warm bathes, long walks, and milk, but, for some reason, it passed, it seems like forever but it will pass. Congratulations, don't nap thru the day, it make it worse.
