This doesn't happen to me a lot, but maybe a couple of times a year. I have episodes when my body doesn't seem to 'remember' to breath on times. I knew I was having problems last night, and my husband (who was sleeping separately due to a cold) came in early and got in bed with me. He told me later that he couldn't hear me breathing -- as opposed to snoring (obstructive-type apnea symptom). I kept waking up and having to take a deep breath. The symptoms actually lasted a couple of hours after I got up and had breakfast. As I said, it doesn't happen a lot, but when it does, it's a bit freaky and not a little scary. I've had two sleep studies (several years ago) which did not show any central apnea episodes, and I haven't recently changed any medications. Does anyone else have these weird little times of it feeling like your body forgets to breathe?
