Some tips on drinking coffee:

First, if you feel obvious discomfort, stomach pain, burning, diarrhea or nausea; palpitations, increased heart rate; anxiety, headache or hand tremors, etc. It is likely that you are allergic to caffeine, so don't drink it.

Second, drinking on an empty stomach before a meal may not be good for the stomach (I drink on an empty stomach anyway, and it feels okay, it may vary from person to person). However, if you drink it after a full meal, it may not have any refreshing effect. Because the effect of eating comes before the effect of coffee. What should I do?

Method 1: Eat some snacks or fruits before a meal and then drink coffee.

Method 2: Drink coffee with a meal.

Third, it is recommended not to add sugar. Modern people have good living conditions, and reducing carbon water is good for health. Brother Feng has been drinking black coffee for 20 years, and it still smells good. If you really can't adapt to it, add some milk, it will be very fragrant.

Fourth (key point), this is the conclusion of Brother Feng and his family's experience. It may not be suitable for everyone, but it must be said and shared with everyone.

If a cup of coffee is 200 ml, add some water to dilute it, and then pour out 200 ml. The refreshing effect of 200 ml before dilution and 200 ml after dilution is the same.
