I've been going sleep around 8 o'clock then getting up at 6-7 but i just feel tired/drained all day like i need to sleep more?

Just a thought: You may have a SLEEP DISORDER ( ie: Sleep Apnea) Ask your PCP if a SLEEP test is indicated~ Hope this helps Dr Z

Need complete workup: There may be many causes including: Celiac disease,(a type of food intolerance, where your body reacts badly when you eat gluten – a substance found in bread, cakes and cereals), Anaemia, Chronic fatigue syndrome, Sleep apnea, Underactive thyroid, Diabetes , Glandular fever, and Depression, among others. Get a complete physical exam including blood work by your Dr. to help evaluate this situation

Seek medical help: Sounds like you're getting an adequate number of hours of sleep however the quality of your sleep may be an issue if you wake up still feeling tired. Seeing a sleep doctor to make sure you do not have narcolepsy or hypersomnia is recommended. Also some viral illnesses can also cause your symptoms.
