30 years, sleeping with a snorer. I keep the drug-store ear plugs in the drawer of my nightstand, and use more often than not. When the decibel level surpasses my plugs, I toss and turn, nudge hubby with an elbow or knee, and/or lift the side of his pillow. Gets him to turn over and quiet down.
My husband also sleeps next to a snorer. He's too chivalrous to ever admit it. But, my snoring can sometimes wake me up. Fortunately, he's a very sound sleeper.
The what ifs kick in. Early years, what if one of my children cried, needing me? Later years, what if they came in way-after curfew and I didn't hear the security alarm? Nowadays, what if I didn't hear the dog, who had good reason, bark? What if I didn't hear a severe weather alert on my phone? I couldn't sleep with noise totally blocked.
