It would be nice to drink coffee but it has adverse effects on me. Even one weak coffee and I feel the negative effects.
Initially I thought it was a caffeine issue but I can drink energy drinks with no change to the way I feel at all.
Even though I haven’t been tested, it points towards being allergic to the actual coffee itself.

Darn! I quite enjoy a good cup of coffee, but any more than just one cup and I get headaches! That's really interesting that you can drink energy drinks with no issues, definitely looks like you could be allergic.

I recently watched this video about whether or not coffee is good or bad for you - quite entertaining!
