Since I was a child, I hated going to sleep. I thought sleeping was boring. Even now, I have trouble falling asleep, since my mind is full of thoughts and ideas. 
This type of mental stimulation is tricky because the mind is in a state of high activity, especially when inspiration strikes. Here are some strategies I learned that might help:

1. Mind Dump or Creative Journal Before Bed

Why it works: Offloading your thoughts and ideas onto paper helps calm your mind by reassuring it that you won’t forget anything.
How to do it: Spend 10–15 minutes before bed writing down all the ideas swirling in your head. You could use a notebook or voice recording app if writing feels too slow.

2. Set a “Creative Curfew”

Why it works: Your brain needs time to shift from a creative state to a relaxed state.
How to do it: Set a time (e.g., one hour before bed) to stop stimulating activities like brainstorming or planning projects. Use that time for calming activities—listen to calming music, do light stretching, or read something relaxing.

3. Wind Down with Music Therapy

Why it works: Certain types of music help slow brainwave activity, preparing the mind for sleep.
What to try: Play Delta wave music or slow-tempo classical music (60 bpm or slower). Consider composers like Debussy or ambient soundtracks designed for sleep.

4. Adaptogenic Herbs and Supplements

Why it works: Adaptogens like ashwagandha and phosphatidylserine can reduce cortisol levels, helping you wind down. Magnesium glycinate and L-theanine are also excellent for promoting relaxation without sedation.
Caution: You can combine this with your supplement plans for longevity, but consult a doctor if you’re considering high doses or combinations.

5. Guided Visualization or Meditation Apps

Why it works: These techniques distract your busy mind while also promoting deep relaxation.
What to try: Use apps like Calm or Insight Timer for guided visualizations. One exercise involves imagining yourself walking through a peaceful, familiar place while deep breathing.

6. Morning Creativity Sessions

Why it works: Scheduling time in the morning for creative work reduces the feeling that you need to hold onto ideas at night.
How to do it: Give yourself 30–60 minutes of focused creative time first thing in the morning. This can help your brain release the pressure to work late at night.
