Yes, snoring and sleep apnea go hand in hand. However being a snorer doesn't automatically means that you have sleep apnea.
Next to that I wanted to assure you that you do not always have to start using a CPAP or have to undergo surgery to stop the snoring when you suffer from sleep apnea. Research showed (http://www.rug.nl/news-and-events/news/news2012/umcg-promotie-michiel-doff) that mild forms of apnea can also be threated by using a anti snoring mouthpiece. I bought mine at duo-confort.com
So, just to be save please go to your GP. He or she will tell you what to do.
