I'm sure that I'm not going to express this exactly, clinically/technically right. Please don't eat me alive.....
Just because you snore doesn't mean that you're breathing is stopping, but everyone is right. It's something to check out, sooner rather than later.
That being said, another thing to consider in how long you wait to get it checked out is the relationship between sleep apnea, and high blood pressure, and diabetes. When you stop breathing, you stop getting oxygen. Eventually your body responds by giving you a little jolt of adrenaline. It's the same adrenaline that is secreted if you were being chased by a bear, and does the exact same thing, releasing glucose into your blood stream to feed your muscles for the flight. Except that you're not running. You're lying still, and the overall effect is like eating donuts in bed all through the night. Your body doesn't care where the sugar came from.
Imagine that someone stands next to your bed and shakes you every so often, maybe a couple times a minute, maybe every few minutes. Not enough to wake you all the way up, but enough to disturb you. The whole time, they're slipping sweets into your mouth. You wake unrefreshed. You don't feel like working out because all you want to do when you get done with work/school, is go home and get some rest. You gain weight. Maybe because of the donuts you're eating all night, maybe because you're too tired to work out. Mix in things that relax you, like alcohol, food, or other drugs, and you just amplify the situation responsible for obstructing your airway. Which came first, the chicken or the egg? Doesn't matter. You feel crappy and stuck.
Sleep studies aren't wonderful, but they aren't awful. CPAP machines (Continuous Positive Airway Pressure?) are one form of treatment. They aren't sexy and take a little getting used to, but they can change your life if you have sleep apnea. Actually waking up feeling rested and ready for the day becomes addictive (even if you like like Gonzo from the muppets, or a take on Hannibal Lecter). I love my auto-PAP machine and don't leave home without it.
