Take the steps to find out if you actually have sleep apnea. Those who snore don't necessarily have the disorder. If you have a sleeping partner, ask them questions about your actions during sleep. Do you stop breathing and gasp for air? That is a sure sign of sleep apnea.
Although you should speak with your doctor about sleep apnea, you can try certain things yourself. If you lose weight and stop smoking, these are good decisions, especially if sleep apnea is a problem for you. You will definitely want to stay away from alcohol and caffeine, along with late night heavy meals before going to bed.
