A BBC Morning Live expert has issued a warning to the millions of people affected by bad sleep. Dr Xand urged people not to turn to ‘illegally’ purchasing a drug that could leave them with contaminated medications and side effects. The expert said it's vital instead to speak to a doctor as they can offer advice and support beyond medications. Dr Xand explained how people in the UK may be getting their hands on melatonin medications “illegally” from others who have travelled to the United States.
