A.S.
Forgive me if i'm repeating i did not go through and read all the answers. I was going to say that you might have sleep apnea, My mother just went through the not breathing and choking spells and she had them nightly. She talked to her dr and she was tested and now she wears a by pap machine. She just wears a mask when she sleeps. She hasn;t had any problems since then. She said she noticed a huge difference in her sleeping! It may not be that you have sleep apnea but it sounds like it's definantly something that doesn't need to be ignored. I hope this helps! good luck with everything...
