The person you sleep with may notice it first. You, or that person, may notice heavy snoring or long pauses in your breathing during sleep. Even if you don't remember waking up during the night, you may notice daytime sleepiness (such as falling asleep at work, while driving or when talking), and irritability or fatigue. You may also notice that you have morning headaches, forgetfulness, mood changes and a decreased interest in sex. The attached humourous poster takes a "tongue in cheek" look at the symptoms of OSA

If you have symptoms of Obstructive Sleep Apnoea, your GP may ask you to go to a sleep center for a sleep study. The tests carried out at the sleep center can diagnose if you are suffering from a sleep disorder including OSA.
