Personally I find coffee fine now after I introduced it in small amounts. One thing I will say is try to have it with lots of milk and along side a glass of fruit juice or a teaspoon of honey. The sugar in these will prevent your stress hormones from shooting up somewhat. If I have an Americano by itself then I get very jittery, if I have it with some kind of sugar then I get the nice energetic and dopaministic effects. Just a thought.
