I have been sleeping in a recliner since the end of the first trimester because I got a bad cold and then after that I couldn't breath out of my nose at night if I was laying down. I use breath rights to help with that, but elevating is essential. I think it would help with heartburn of course too. I also take sublingual b12 daily, which I have found helps me sleep well at night, but don't take it right before bed because it is also known for giving an energy boost. I take it during the day. I have also heard taking magnesium daily can help with sleep. As an added bonus it helps with preventing constipation too. When I tried to sleep in bed I'd just be up half the night, so I gave up on that idea.
I had terribly insomnia at the beginning of this pregnancy. One of the first signs I was pregnant. The sublingual b12 has fixed that. I forgot to take it for a couple weeks and the insomnia came back. I started taking it again and it went away. So, I'm sure.
