The page does not address alcohol, so this is general guidance, not a HoneyFil rule.
Alcohol disrupts sleep, dehydrates and is processed by the liver. Some herbal ingredients have rare reports of liver problems, and ashwagandha is one that has been discussed in this respect. Alcohol can also add to drowsiness from calming herbs.
Since amounts are not published, nobody can say how much of any ingredient you would add to that picture.
Keep drinking moderate, or avoid it while you evaluate, since alcohol blurs your energy and sleep log. If you drink heavily, have liver problems or take medication, ask a doctor first. Stop and seek medical advice if you notice yellowing of the skin or eyes, dark urine or persistent stomach pain.
