Snoring certainly can break up a relationship, but it shouldn't if a couple makes every effort to work it out. Serious snorers and those with sleep apnea ruin a partner's sleep. Most advertised cures help only slightly, if at all for this group. CPAP machines are not well tolerated by a lot of people who say they are claustrophobic. Suggestions such as sewing a tennis ball in the back of pajamas to prevent back sleeping, weight loss, and not drinking alcoholic drinks around bedtime
are helpful hints for moderate snorers. Seperate bedrooms combined with wearing earplugs is the only solution for others. Open communication, respect, and loving affection are key to saving these relationships. Otherwise, the resentment can drive them apart.
