Caffeine helps improve alertness, alertness, memory and concentration. But drinking more coffee than you're used to can produce a similar dose of stimulant and cause jitters. For people with anxiety disorders, caffeine can worsen symptoms such as sweaty palms, heart palpitations, and tinnitus.
2.Exacerbates high blood pressure.
Caffeine is often combined with other simple analgesics because of its pain-relieving properties, but if you take large amounts of caffeine over a long period of time, if you already have high blood pressure, using a lot of caffeine will only make your condition worse. Because caffeine alone can raise blood pressure, and when combined with emotional stress, it can have a dangerous synergistic effect, so people at risk of high blood pressure should especially avoid drinking caffeinated beverages during stressful work times. Some people who drink coffee all year round think they are immune to the effects of caffeine, but this is not the case, as one study showed that blood pressure can rise for up to 12 hours after drinking a cup of coffee.

If you can enjoy it in a reasonable amount, you can still do it without choking.
