Sure. When I have a night of poor sleep or anticipate one, I usually take 6 grams of BHB salts in the morning on an empty stomach. You can work your way up to a maximum of 12 grams, but I would advise caution since it can cause diarrhea. I would start by buying the cheapest product (nutricost) you can find online; if it costs more than $80 for ~300g, then you're probably getting ripped off. I noticed that I have very lucid dreams and experience strong hypnagogic jerks when I take this supplement.

Here is some literature that I've perused to support my experimentation with BHB salts:

1. β-hydroxybutyrate is a metabolic regulator of proteostasis in the aged and Alzheimer disease brain (https://www.sciencedirect.com/science/article/pii/S245194562...)

2. Refueling the post COVID-19 brain: potential role of ketogenic medium chain triglyceride supplementation: an hypothesis (https://www.frontiersin.org/journals/nutrition/articles/10.3...)

My motivation for pursuing this was protracted sleep disturbance from long-covid.
