Cold weather can make getting my deep breaths uncomfortable, but doesn't seem to make me need more of them. I'm not allergic to anything except mushrooms (and that causes nausea, not breathing problems). I've never woken up in the middle of the night (that I know of) with breathing problems. I sometimes breathe oddly when afraid/in pain, but it doesn't seem related. Eating too much at bedtime doesn't do anything that eating too much at other times doesn't.
