This week I ran an experiment with nicotine via Zyn pouches. I don't advocate using nicotine given its addictive properties, but I wanted to see if Zyn would help suppress the urge to eat late at night without negatively impacting sleep quality.

For me the answer appears to be yes. Nicotine as an appetite suppressant has been widely studied and is well known. My sleep tracker showed that, unlike alcohol and caffeine, nicotine did not prevent me from enjoying a long night of deep and uninterrupted sleep.
