Can I have tea and coffee together?

Coffee time to drink coffee is best after breakfast and lunch, because this can promote gastrointestinal motility, help digestion, can decompose the high-calorie, high-fat food eaten, and will not be like drinking coffee on an empty stomach, causing irritation to the stomach. It is best not to drink coffee after dinner, for fear that it will affect sleep. If you want to stay up all night drinking coffee, you may accidentally drink it.
