I am 50 years of age male. I feel sleepy always at any point of time. It is a problem with me since my child hood. While driving or travelling or talking or studying I feel sleepy and feel embarrassed among others. I am a normal human being, non-diabetic, no blood pressure, cholesterol level is almost normal excepting LDL i.e.129 (as per last report 15 days back ). I am very active, go for regular exercise, yoga to keep me fit. Pl. Suggest me to over come this problem. I also want to add that I never face sleeplessness during night even after drowzing hours of 3 to 4 every day. Is it a neurological disorder? Pl. Suggest.
