Why does caffeine effect me differently ....?

When I drink two (2) or more cups of coffee my hands shake and my heart races. That is why I only drink decaf coffee. Yet I can drink Diet Pepsi, twice the amount than coffee and yet the caffeine in there does not bother me. I know caffeine is caffeine, but why does it bother me more if I drink coffee?

    Instant coffee (8 oz) 70 mg

    Decaf coffee (8 oz) 1-5 mg

    Tea - black (8 oz) 45 mg

    Tea - green (8 oz) 20 mg

    Tea - white (8 oz) 15 mg

    Coca Cola (12 oz can) 34 mg

    Pepsi (12 oz can) 38 mg

    Barq's Root Beer (12 oz can) 22 mg

    7-up (12 oz) 0 mg

    Do you eat before you drink coffee? If I do not eat I get the shakes but I can drink mountain dew without anything and drink a lot of it and I am just fine. Coffee also has way more caffeine than cola's.

    Maybe a mental thing. Lots of drugs' effects are mental reactions brought on by yourself. Try drinking coffee and thinking it's not going to affect you like it does? Trial and error, ftw?
