Hi. Welcome To HealthcareMagic
Are you over weight? Do you snore in night? Do you feel sleepy in time? Do you have any other medical problem?
It could be sleep Apnea
. Consult your MD for screening. If some of the answers are yes, you may need sleep studies.
Also I want to ask you, do you have any Psychological problems, like depression
and bipolar disease.
