I've read the reviews and I agree that Yuban is absolutely the best coffee but at $100 for 12 cans comes to over $8 a can.  That's $3 more a can than I pay at my local store.  I don't understand the high price?

I tried this gum after Trident cinnamon became hard to find a couple of years ago.  (Trident told me that they were overhauling the plant that made the gum so it was in short supply but it would be back.)  I quickly discovered that the Flare 5 was far superior to the Trident and I haven't looked back.  It does last a long, long, long, time.  Unfortunatley, as other reviewers noted, it has become very hard to find in stores.  Trident cinnamon is everywhere but now I don't want it.  Amazon saves the day again.

What's in this stuff?  Where's the list of ingredients?  I don't eat anything unless I know and approve of what's in it.  For example, although this product's description says it contains no sugar, it does not say if it contains any artificial sweeteners, which are also bad for you.  For one thing, aside from tasting awful, artificial sweeteners often cause horrendous intestinal cramps and diarrhea.  In addition to having long ago given up the eating of sugar and sugar in all its guises (e.g: "natural" cane juice, fruit juices, "raw" sugar, "organic" sugar, etc.), I also stopped ingesting artificial sweeteners of any kind.  So, what's in this stuff?
