Coffee is really the only caffeinated thing I consume. I learned after my (relatively mild by some stories I've read) floxxing that caffeine + flox drugs are a bad combo, and I was very much a coffee person, so of course I combined them. My skin has been more sensitive in general ever sense, and attempts to drink regular coffee usually lead to that pins and needles sensation.

On the upside, I've discovered a great decaf: Slow Motion from Counter Culture. So hard to find high quality decaf, and I'm glad I was recommended this one. I actually drink more coffee now than before because I've been able to switch to decaf.
