Ms Arielle, my DH was able to tell me that I would stop breathing, and he would nudge me to get me to breathe, but I also noticed it myself. I would wake up suddenly gasping for air. I guess if you had mild symptoms this could happen without you waking up, but I think I have a pretty moderate to severe case. I used to be able to sleep in my recliner while watching TV but I can't do that anymore. I keep jerking awake, because I'm not wearing my CPAP. I don't take it with me when I'm in the hospital but they put me on oxygen so I can sleep.
