Melatonin: Average +2.2 (3 reviews) (SD 6.6); works well for some, others feel groggy the next day
An observation for anyone using Melatonin: the effective dose is reported to vary between individuals by literally a factor of 100. If it produces grogginess the next day then halve your dose and repeat as necessary. Some find that the dose that works for them is as low as 0.1 mg. In my case I tend to experience next-day grogginess at approximately 6mg, and it also reduces the duration of sleep. 0.5 mg to 3 mg seems to work with no noticeable side effects except that I am less likely to have procrastinated away sleep until 3am.
