Same here. In fact, when I sleep for 8-9 hours, I am profoundly less sharp and productive.

That said, I'm only 20, and I don't want to wreak havoc on my future health. Difficult stuff.

Similar here. These days I usually sleep around 6 hours (used to be 5.15ish). If I sleep longer repeatedly I start to get migraine like headaches. Weird, but at some point I decided it's not worth worrying about.

Have a large glass of water before sleep (real water, no soda or juice). A lot of issues and tiredness after long sleep is caused by dehydration.

Sadly I don't think that's the case for me. I drink too much water if anything.
