it is important to determine what exactly you mean by you claiming you dont get sound sleep. because you claim that you sleep well. its important to assess the duration of sleep, the timings of your sleep, difficulty in initiation of sleep, difficulty to sustain sleep, nightmares or night terror, sleep apnea (difficulty in breathing while sleeping), consumption of stimulants (nicotine, caffeine) and other sleep habits.
but it is important to understand and realize that sleep alone do not determine whether you have a refreshing or an active day ahead of you, there are multiple physiological and psychological factors which does so.
a lot of people now days complain of fatigue and tiredness which may be offshoots of other malfunctions or disturbances in life and general functioning and lifestyle. sleep merely contributes to adequate energy levels during day times, it doesn't dictate or determine.
its also important to get a through physicians advice since a lot of medical factors may influence in this condition too for example
thyroid levels which a medical probationer is better at managing.
you may be under the false impression that sleep is the cause of your woes which is unnecessarily increasing your anxiety level and further disturbing your performance and functioning.
