Thanks for your question on HCM. I want to know few things 1st. Your weight? Have you consulted any doctor before.? If you are obese than chances of obesity associated sleep disorders is there. In this due to excess fat in neck there is night time awakening and day time sleepiness. And this can be diagnosed by sleep study. So consult pulmonologist for this. And if you are not obese than you need to consult psychiatrist for your sleep deprivation. Depression can be the cause. You need psychiatric consultation for proper diagnosis.
