My tips are a bit weird again. However, I never had problems with falling asleep.

Lots of exercise throughout the day (hopefully your knee will be ok soon 🫂).

Intermittent fasting, so no eating after 8 pm. Preferably no coffee, at least not after 4 pm.

Time in nature.

Magnesium actually helps. No sugar if possible.

No media an hour before sleep.

Meditate in the evening, take a warm shower, maybe a long walk.

Get up early in the morning.

How does that sound? Pretty exhausting, isn't it? 😂
