Has anyone here managed to reduce the frequency of waking to pee at night (e.g. by controlling liquid intake)? For me it’s 2 times/ night with difficulty going back to sleep so fairly huge disturbance.

Couple of (fairly obvious) things that have helped me: - don't drink liquid before going to bed - use the restroom before going to bed

Often (at least for me) the feeling of needing to pee is greater than the actual need to pee. Realizing this, it's easier to hold it in until morning.

My vitamin D level is only optimal when taking an average of 11000 IU / day (D3 + K2). It hasn't improved my sleep quality. As an example, I woke up at 3:30 am this morning and feel like I haven't slept at all.

Isn't that way into overdose territory?

Yes, taking that much vitamin D every day puts you at risk of developing dangerously high blood levels. One of the things it can do is screw with your calcium levels which screws with your nerves which can, for example, make your heart beat abnormal.

Don’t do this without the advice of a doctor and regular serum level testing.

Honestly, OTC quantities vary depending on what is legal where you live. It has been 8-9 years since I lived in the US but nevertheless: At the time, you could buy 1000-2000iu strengths. I worked at a large pharmacy chain and stocked vitamins weekly. Then I moved to Norway. One strength is sold in most stores - 400iu per tablet. You might be able to buy stronger in the pharmacy, but I had to have a prescription for a…

It would depend on individual ability to metabolize D3 and amount of outdoors sunlight and the extent that local food is fortified with D3. So everyone's situation is unique. I'm confident that 2,000 IU daily is safe, though.

Not just fortified with vitamin D, but also the things that contain it naturally. Like seafood.

If anyone is struggling with sleep, I highly recommend episode 1-3 of the Huberman Lab podcast ( https://www.youtube.com/watch?v=H-XfCl-HpRM ), it has literally changed my life. Dr. Huberman is a Neurobiologist at Stanford and explains the science of sleep vs just telling you to not look at bright screens at night. I struggled with sleeping for 20+ years, now I easily wake up early. The biggest game changer: Sunlight…

For me I had to also really avoid light at night. F.lux or Windows Night Mode is not enough. You gotta suffer with strong indoor lightblocker glasses, or use e-ink or something at night.

You just made me feel I might be on the brink of a startling discovery. Holy hell, I have tried a lot to improve sleep. I haven't tried this. And while there was one confounding variable in my case with camping, it did indeed shift my sleep rhythm to the day/night cycle of the country I was in!

In my city during winter the Sun rises at 8:30am... so I'm afraid that won't be possible for people wanting (or needing) to wake up too early.

Do you think one of those "simulates natural light" LED lamps are actually equivalent in terms of faking real sunlight?

I needed better sleeping and tried various things. In the end I stopped drinking coffee and tea. For me its now just hot or cold water, sometimes a herbal tea, and an occasional beer or orange juice.

First caffeine-free weekend I had terrible headaches, than came weeks of strong urges (I felt I was an addict). In these weeks I just fell asleep on the couch or even at my desk at work. I slept a lot these weeks, during the day, early in the evening, like my body had catching up to do.

Now I'm fine, I sleep like a baby. I feel really good and have strong concentration.

On moments I have a 'coffee urge' I take a little walk outside, for 10-20minutes. My colleagues know by now, I'm the guy who goes out once or twice a day for a little walk...

Try it for a few months!

I keep reading about these “IU”s on HN, what on earth are they? Here in the uk you just buy “Vitamin D” and take one pill per day. No fine-tuning, unless you need specialised therapy perhaps.

International units. OTC quantities tend to be quite low, e.g 300-400 IUs, which aren't sufficient unless you're also getting daily sunlight not through a window. 1000-2000 IU is better - widely regarded as safe and no cases I've ever read of of hypervitaminosis, but it's above usual OTC doses. 4000+ daily is pushing it and I have read of cases of toxicity above that, but if you're struggling to get serum levels up t…

One thing to be careful about in selecting a supplement is the reputation/testing of the brand since they are loosely regulated. Specifically, how accurate and even are the doses in each batch and capsule? 50 micrograms is small quantity to measure accurately and consistently unless the right equipment and process is followed. There have been a number of supplements and manufacturers over the years who's doses from batch to batch or even capsule to capsule vary wildly.

Another one of these "eggs are good"/"eggs are bad" flip flops that happens every few years. Before this the "science" was that too much vitamin D disrupts sleep. In fact it seems to have disrupted mine. It's 4AM, and I can't sleep even after taking a MJ brownie. I take 2000IUs daily and my values are "normal" now. And yet I've been suffering from insomnia shortly after I started taking this supplement. Who do I beli…

I think I've read that THC usage can affect long term sleep quality...
