How caffeine impacts your body

Some people can't break down caffeine well. They may experience increases in blood pressure or unpleasant symptoms after drinking coffee. These symptoms can include feeling jittery, difficulty sleeping, headaches, and muscle twitches.

How alcohol impacts your body

In people who are sensitive to alcohol, alcohol breakdown is inefficient and causes the buildup of a toxic compound called acetaldehyde. Symptoms of alcohol sensitivity include flushing, nausea, headache, and fast heart rate.
