I hear ya. I'd already given up coffee (mostly) but I had one a few weeks back and ended up on the couch, sick as a dog, for a WEEK while my stomach told me just how much this whole coffee thing wasn't working for it. That was fun.

I have been a herbal tea drinker for years. I recommend ginseng tea, which isn't great on taste, so I throw in another bad of rooibos, and a teeny nip of honey. I'll miss coffee fondly, but I wouldn't trade it.
