@ehBeth,
												They sell that "Bark" candy at "Wild Birds Unlimited" stores. hen I asked the salesgirls why they carried em, they hqd not a clue.The Bark brands alo made a bag of busted up chockie with toasted coffee beans. You got a double hit, NO, actually youd get a triple hit
1.You'd get two  hits from the related alkaloid "jack-up-juice", of CAFFEINE  from the coffee beans, and THEOBROMINE, from the chocolate 
2. And  then, on top youd get a skull pounding sugar high from the candy matrix
 However, that aside, Im loving sour tastes in candies lately.  When I ws a kid, my  favorite cousin and I would sit around on Easter and, as I recall, we would see how many PEEPS we could stuff in our mouths  and eat without gagging.
