My average recently seems to be around 4. Last friday I got 2 and on the weekends I can sleep 12+. I'm really considering seeing a doctor just in case, because I've started resorting to very bad sleep aids and on some occasions there have been times where I am prevented from passing out in-office because i dropped my phone while nodding off. Im also pretty much unable to concentrate worth shit anymore. I'm willing to accept that its probably lifestyle issues, but idk. The times I seem to be "naturally" tired and awake seem a bit strange.
