Melatonin is certainly useful for some people with insomnia and those experiencing jet lag (particularly when traveling east).

Some considerations:

• melatonin is available over the counter in the US but requires a prescription in the UK
• UK NHS dosage is typically 2mg initially
• higher doses are not necessarily more effective than low doses
