Try RonL--he roasts his own , and may have something. Now then--Try Gevalia , or a Kona blend. I've been there and done that. If you notice--cheap coffee--i'm sorry , folgers is ---you'll find a layer of oils floating on top. IMPURITIES --period . If you try Gevalia --and grind your own , pls. ---you'll notice an absence of that. No guarantees , but i'll suggest you'll have less problems. If i had to drink decaf , i'd just quit.
