My 85 yr old grandmother mentioned she had the best night's sleep she's had in months after having a Pad Thai at a restaurant for an evening meal with us recently. This particular Pad Thai comprised of rice noodles, beansprouts, king prawns, spring onions and some peanuts, garlic and lime (well there was also a light mild sauce but I don't know what was in that).. is there anything from those known ingredients that stick out to you that may be particular high in a nutrient that promotes restful sleep?
