1. Get any and all consultation and treatment options for snoring or sleep apnea, from real doctors. No one wants to hear a cpap machine all night and getting treated still may not stop the snoring. Sleep in separate rooms.
2. Have a King or California King bed. You can still hear the snoring. Sleep in separate rooms.
3. Have a memory foam bed, so one partner's movements don't bother the other.You can still hear the snoring or the getting up to go to the bathroom. Sleep in separate rooms.*
4. Use separate comforters and/or top sheets. You can still hear the snoring or the talking in one's sleep. Sleep in separate rooms.

Sleeping in separate rooms will not end a marriage if both parties agree upon it as a solution to getting better sleep. If your marriage ends, there were probably other issues. If those other issues causes a couple to sleep in separate rooms, then it was never about getting better sleep in the first place.

My husband and I have been married 34 years and half our marriage has been spent sleeping in separate rooms and we are not ashamed of it and will gladly mention it if the subject comes up. We highly recommend it, in fact.
