Two hours before going to bed, I drank a bottle of 1.2 Sprite and half a bottle of Coke. How can I stay up and have nightmares all the time?

Eating food or drinks before going to bed will aggravate gastrointestinal digestion and prolong digestion time. When you drink a bottle of 1.2 liter Sprite and half a bottle of Coke, your stomach will be fully digested. When you digest your stomach, other internal organs will also cooperate with your stomach, causing your brain to be temporarily unable to adjust, and it is not easy for people to fall asleep.

Therefore, don't eat before going to bed, especially when you are full.

As for nightmares, it is because the brain can't get reliable adjustment time, and people don't enter a deep sleep state. It may be because the stomach is digesting, the blood circulation is accelerating, and some parts of the brain are moving, which will make people enter a hazy state, like sleeping instead of sleeping, so that they have some messy dreams. Dreams are illusory. They are the brain's self-regulating response. When people are tired, weak or overeating, they have many dreams.
