Hello... I understand your situation, based on the history you have given I think you should know that human body require atleast 6-8hrs of sleep.. Without that a person will be irritable, drowsy, difficulty in recollecting recent things if severely sleep deprived, person feels easy tiredness...I would suggest him to do some morning brisk walking, meditation and yoga to destress.... There are certain hospital which has sleep clinics who can address your issue kindly visit that center...Consult nearest psychiatrist they will do the needful.
