It's likely the caffeine content. This may be an indicator that you need your adrenals tested (4 point saliva test), or you just may be sensitive to stimulants right now. I would suggest you find a decaf coffee to try to see if that helps any.
Since my adrenals crashed, I've had to avoid ALL caffeine and drink a coffee substitute. Not fun, but at least my adrenals can heal!
