<i>I have melatonin lying around. I&#x27;ll have to test adding it to the routine next time</i><p>I&#x27;ve tried regular Melatonin while hungover and though it helped with the head-pain it did what Melatonin is meant to do - it put me to sleep. The slow-release stuff is better if you need to go to work or have plans that day. It also has a lasting effect as a result of being slow-release. I found that taking it on the night of the drinking before bed didn&#x27;t help - it&#x27;s not an effective prophylactic.
