Helping partner's snoring

LT

I am right on the verge of getting him to go to the doc. When he first moved in, he never snores at all. Now, we can't even sleep in the same room together. We have tried different pillows, the breathe rite strips, moving positions, changing sides. He even bought a mouth guard, and it is doing squat to stop it. I'm at my wits end. I am at least somewhat comfy on the couch. The only spare bed is in our baby's room, and she has become such a restless sleeper, the slightest sound rouses her, so I can't really sleep there. Any suggestions? (As of right now I can hear home snoring from my couch from the bedroom).
