Up to 30% of people may have sleep apnea. I recommend everyone to get at least an at-home sleep test. In-lab is much more difficult to get insurance to cover, but you could pay $1,500+ out-of-pocket.

It is a horrendous condition that will ruin your life.

A few years ago, I stopped setting an alarm clock on a regular basis. Now, I just sleep as long as I need, which is usually 8-9h a day. I struggled with sleep for years, but now I sleep good.

The risk with an inconsistent waking time is shifting forward the circadian rhythm, if you sleep in later and later. When that occurs you'll fall asleep later as well, or wake up more often. A wind-down period ahead of bedtime can also offer some flexibility, if you happen to have enough sleep pressure to fall asleep earlier some nights.

I have a very weird problem/issue, maybe someone can help. In my school days I used to maintain a dream diary, where I would note down every dream I had after waking up. I stopped doing that when I got into college, but dreams never stopped and I never stopped analysing and trying to remember the dreams. Fast forward to present time (10 years from school), whenever I want to wake up i.e. after 6-7 hours of sleep I ca…

Put your alarm clock on the other side of the room.

I did this back in high school. Turns out at some point I was able to wake up, walk to the computer (which I used as an alarm clock), stop the alarm, get back to sleep, and forget everything.

Given the time span, I assume the answer is, "no," but are you taking any dietary supplements? DMAE? Galantamine? If yes, stop taking them (after consulting with an appropriate heathcare provider).

EDIT: My own experience with DMAE is that it made some dream memories hard to distinguish from reality. Did that happen only in a dream? I wasn't so sure sometimes.

I wake between 11:00 and 13:00 for years now. And I go to sleep between 2:00 and 4:00.

Interesting. I found after some trail and error that I'm more rested and perform better on less than recommended 8h of sleep. My sweet spot is somewhere around 7h. Fitbit "magic" sleep score also seems to confirm that (better sleep score on less sleep). I also found that stress is the biggest factor in getting good night sleep. When stressed I can sleep 8h and still feel bleh. I wonder if 8h of sleep is the cause of…

I've settled for somewhere around 7.5h as I find this is less likely to lead to sleep onset or maintenance issues. Trouble falling asleep can shrink the total time even more, so I like to avoid that risk.

I countered this by setting a go to sleep alarm. Alarm goes off, time to wind it up and head to bed. I do have a morning alarm (multiple of them) but I've been waking up before they go off.

Here's a cooky idea:

When you wake up, force yourself out of bed, and immediately go wash your face, then do some pushups or go for a run around the block.

You're in charge of yourself, if you want to wake up, get out of bed and do it. How old are you?
