Do you snore?  If it is just snoring it may be an irritation to your partner.  Sometimes snoring is transient as in cases of extreme tiredness.  If it is persistent, then it should be addressed.  Snoring may be a sign of different underlying medical conditions.  If you stop breathing while you are asleep, it is called sleep apnoea and that is a medical condition that requires further investigation.  Hence, just snoring is boring, sleep apnoea is not!
