Decaf Tips?

So long story short, for legitimate health reasons I can no longer have caffeinated anything. Pretty much anything above a decaf coffee or a chocolate bar is unsafe.

Ive been doing decaf for a year now and its been ok but I was wondering if any of the experts had any suggestions regarding brands, methods, ect. that youve found is best for improving the taste.

I reside in Canada if that makes any difference.
