If you are ok then grab a bite, just to help your stomach. It can be something as simple as a handful of almonds.
Although generally considered an energy-boosting food, bananas are rich in magnesium which relaxes muscles and they also contain serotonin and melatonin, which encourage sleep. Oats, as well as being yet another food rich in vitamins, minerals and amino acids which promote sleep-inducing melatonin, encourages insulin production and naturally raise blood sugar. Just one teaspoon of honey is enough to stimulate the release of melatonin in the brain and shut off orexin (which keeps us alert), thus helping you to wind down.
