Health Tip: Signs That You've Had Too Much Caffeine

(HealthDay News) -- You may relish that first cup of coffee in the morning, then a few more cups throughout the day. But if you've had too much caffeine, which is a stimulant, it can lead to significant side effects.

The National Sleep Foundation offers these symptoms of excessive caffeine consumption:

• A decline in fine motor coordination.
• Inability to sleep.
• Headaches.
• Anxiety, increased nervousness and feeling dizzy.
• Feeling irritable.
• Increased heart rate.
• Excessive urination.
• Feeling down once the caffeine is out of your system (a caffeine "crash").
