Seems like I've started to snore.
 

I can hear myself. It's really upsetting. Snoring is bad! I wonder why this is happening all of a sudden.

Yeah, I snore too, apparently. I don't hear myself though. I only know it's been happening when I'm woken up by a little shove from my SO, while he's trying to hear the TV.

don't smoke tobacco any longer; haven't smoked much of anything lately; don't drink to excess; am overweight, but I always have been. Am old. My bed/mattress is fucked up and I need a new one.

maybe it's allergies. I often feel slightly short of breath in the morning. Maybe that's not quite it--but I feel almost wheezy.

Apple cider vinegar.

That's very helpful.

Age and overweight will cause it
It will do you a lot of damage, high blood pressure, heart diseaes and diabetes they all seem to go together.
Sure which causes what I dont know

It does sound like allergies. Maybe you should change pillows to start?

Maybe things change as you get older?

I never used to snore, but I do now.

I drool too :D Im such a catch

Neither snoring nor apnea are good for sleep or health. Sometimes I sleep better on the couch, half leaning on the arm. That makes me think it might be a bed or pillow thing, as suggested in the other comments.

My mom has had a huge problem with snoring for years, nothing seemed to helped. She had surgery to remove a tumor on her pituitary gland where they went in through her nose, after that the snoring was much much better. For a few years. This past year she did a sleep study program and is on some breathing machine at night. She's doin alot better. You might want to try a sleep study.
