And I'd just like to add, don't underestimate the effect snoring has on your partner. If severe it can drive someone litterally crazy. If there's anything you can do to stop or at least reduce the snoring, do it not only for you but for your partner. Telling her to use ear plugs is likely to p*** her off (it did me).
I would suggest you see your GP about it. It might only be a mild case but sleep apnoea increases the risks of heart problems, it also affects your blood pressure and all sorts of things with the worse effect being that you feel more and more tired over time to the point where you fall asleep at inappropriate times.
My husband started with it about 3 years ago, scared me to death the first few times I noticed. He got officially diagnosed with it last month and has a severe case: he stops breathing and wakes up 70 times an hour (you don't realise that you woke up as it's micro wake) so he needs a CPAP machine. It's not the best of news but if it allows him to have proper nights sleep and to feel rested in the morning it's all worth it.
