Caffeine Can Cause the Jitters If Your Body is Sensitive to Caffeine
If caffeine’s effects are giving you the jitters, you may be experiencing additional side effects. These include anxiety, changes in mood, heart palpitations or inability to sleep well. If your caffeine intake and jitters interfere with your daily life, you may wish to reduce your overall intake. Because your body can become accustomed to drinking caffeine, you may have to reduce your intake slowly to avoid adverse side effects such as fatigue or headache.
