text: i sleep 8 hours/day but still fatigue? i sleep 7-8 hours/day and have been trying to get more hours to sleep, even on sunday i can sleep whole 15 hours. but i found that i still feel "fatigue" no matter how long i sleep.   is there any pills/exercise to do to get our energy back to 100% on the next day ? i heard of yoga, meditation, but i am not sure what steps of yoga or meditation (in simplest way) to do before sleep? and for pills wise, what pills or food should i take to improve my condition ? consult your doctor.  a thorough history, exam, plus or minus blood work can often yield a diagnosis.  and only by finding what is causing your fatigue can your condition improve.  the symptom of fatigue can be caused by hundreds of reasons.  you relate you fatigue to your sleep but if something was going on you would be fatigued irregardless of how much sleep you get.  in other words, it may have nothing to do with your amount or pattern of sleep.  the things that come to mind are sleep apnea, anemia, diabetes, thyroid disease, depression, chronic fatigue symptom.  these are just a few things that come to mind.  please seek consultation with a doctor.
