I usually get up at 8:00am for work but the last couple of weeks I keep waking up at like 6:45-7:00, so I usually just go back to sleep for another hour. Lately I've been feeling tired and sluggish and I'm wondering if it's from my sleeping patterns. Would I be better off just getting up when this happens or is it better to go back to sleep and get an extra hour of rest? Thanks!
