Is caffeine giving you the jitters?
(HealthDay News) -- Caffeine can provide a little "pick-me-up" if you're struggling to stay awake. But this common stimulant, found primarily in many coffees and teas, also can cause a number of unwanted side effects.
In addition to the jitters, watch for these potential side effects of caffeine:
- dizziness, nausea, headache and/or insomnia.
- anxiety or irritability.
- rapid heartbeat.
- reduction in fine motor coordination.
- urinating more than usual.
