Nope, no flavorings to the cooking. I don't think I'm melatonin deficient, I've just been using it to get back to a more regular sleep schedule ( falling asleep around 10 or 11 instead of 1).

I used 1-3 tsp of vanilla extract (41%) alcohol. And like 5-10 drops each of stevia and melatonin (11%) alcohol. It certainly can't be much alcohol.

And for caffeine, I've been having around 8-12 ounces of tea. So 30-60 mg of caffeine.
