sleeping in excess of 12 hours a day is definitely too much.
90% of people sleep 7-8 hours per night. 5% of people sleep more than that, 5% sleep less. I find I'm toward the unfortunate 5% now. I haven't needed to sleep 10-12 hr since in the 1st or 2nd grade if I recall.
I also thought the older a person gets, the less sleep he/she may need. A man claimed to have lived over the age of 200 in China said his secret to living a long life is to "sleep like a dog" "move slowly like a turtle", but most important "sleep a lot, half of a day (12 hrs ) " etc.
Too much sleep seems to be a marker for some disease. People who naturally sleep a lot more than otherwise happy and healthy people who only need 5-6 hours tend to not be all that healthy.
What does anyone think about an analogous form of CR to sleep? let's call it SR (sleep restrict.). CR does lead to less sleep I think? I don't have 1st-hand experience since not meditating on doing CR longterm
If supplement caffiene and piracetam , I find they act better in your system if you don't eat 100% full meals every single meal, the downside would be more vomit-inducing instincts, bad vibes and feelings
