What is the best cure for snoring ( Apart from divorce!)?

Answer
It’s possible to treat snoring through lifestyle modifications such as losing weight, quitting smoking, changing sleep habits, and avoiding alcohol and sedatives before you go to bed. If snoring is due to nasal congestion, nasal strips, decongestants, or nasal corticosteroid sprays may be used. If these modifications do not improve the snoring, then it is time to see a doctor.
