Do you get the same reaction from coke?
Sounds like you have allergies to caffeine.
I drank a lot of tea and coke throughout my life, and now I can't drink either or I'll
get sick to my stomach. Puffy eyes and dark circles is a sign of allergies.
The worst thing about coffee most people aren't aware off is, that coffee coats the lining of the stomach. So if you take Vitamins or herbs with or after drinking
the coffee, you won't be getting the benefits. Ever notice how you get sick more often then others even while taking the vitamins? I know it can be hard, but stop
the caffeine for a week and see if you don't start feeling better. I know those caffee headaches can be a killer.
