You've got my sympathy. My husband snores terribly, and more so if he's had a drink - which isn't often. The noise is so bad that when we've been on holiday, people in the next room of the hotel have banged on the wall!
He usually sleeps in the spare room, which is the one the GC use when they stay.
He's reluctantly tried nose strips and mouthguard things, a throat spray, and I've tried earplugs (I can hear him with those in, he's so loud) I've suggested he sees the GP (obviously not at the moment), but he's really selfish and refuses to go.
He is 61, fit and healthy, off work due to furloughing, and is currently snoring on the settee. 
I'd suggest you make your man sleep in a different room. The lack of sleep will do you no good.
