Do you feel sleepy during the day? Do others complain about your loud snoring? You may have a common sleep disorder that causes your breathing to be repeatedly interrupted during your sleep cycle. This disorder can quietly drain your energy levels and reduce your quality of life, not only causing snoring and sleepiness but even bringing on headaches, mood changes and other health problems. Sufferers sometimes try to lessen these symptoms by making lifestyle changes such as weight loss, avoiding smoking and alcohol, and changing up sleeping positions, but this doesn’t always work.
