Hi there, i travel quite a bit and I use Melatonin whenever I need to reset my internal clock. The one I buy is also from Watsons and its supposedly an herbal formulation so i'm guessing it's safe. But what capacity are you using it under -- are you pregnant or nursing? If so, best to check with your doctor first.
Yup I have. It's natural. I take it whenever I need to have a flight to a different time zone
Eat pistachio after dinner also.. It helps sleep
