Not liking this..

I get heart burn around the same time every night and I also become so uncomfortable. I can't sleep..last night I went to sleep at 3 am and then woke up in the morning with a really bad headache (8:30am).. I really hope I can get some rest tonight. Any suggestions with the heart burn? It so bad I wish I could throw up but I don't.. Also any tricks for comfort I am having shortness of breath do to being tiny and as I get closer to the end I'm just miserable.. Any helpful advice would be greatly appreciated!
