Coffee Side Effects. What are the side effects of the drink of the gods that is coffee? Well, according to the Mayo Clinic, if you over-drink coffee (more than 500 to 600 mg) you might feel any of the following:
- Stomach upset
- Fast heartbeat
- Muscle tremors
- Sudden urgency to remove shirt.
Hah! Does one really have the sudden urgency to remove one’s shirt if s/he’s drinking too much coffee. Not really. We added that as a joke because if you search “people drinking coffee” this shirtless photo of Jesse Metcalfe drinking a mug of coffee turns up on Google.
