Generally I'm in bed by 11PM and up around 7-730AM. My quality of sleep varies though. Like last night I went to bed around 11 and got up at 6AM, but that was because I slept right through. I usually wake up at least once, maybe around 4AM to take a piss
My apt is loud as fukk though... w/a comfy bed and no noise all I need is like 7 hours. When I was at the resort in Mexico me and wifey were in bed between 11-12 and up around 6 every day, feeling extra refreshed. So the quality of sleep is big too. All the sleep in the world doesn't matter if its shytty
