Good sleep hygiene definitely contributes to better mental health. Not bi-polar, but struggle with depression. After my last crash a few years ago, I was left curled up on the floor just saying I wanted to die. It took me about a year to recover from that, and during most of that year I usually slept at least 10 hours a night. It was definitely part of my recovery.

These days I'm usually between 7.5 to 8.5 hours. Having had a history of insomnia I try and get on top of any sleeplessness issues pretty quickly. Usually just taking melatonin for a week if I have a couple of nights in a row with difficulty getting to sleep will fix it for me.

Also, if you suspect you might suffer from sleep apnoea then get it checked out. The quality as well as quantity of your sleep is important.
