I am very sensitive to caffeine and recently switched to decaf only after drinking coffee daily for 20+ years. I drink mainly Mountain Water Processed coffee, which is the same thing but from coffee sourced in South America. It is roasted by a local roaster in Minneapolis. I honestly can't tell the difference between the decaf and regular (except for the lack of caffeine).

Also, SWP or MWP coffee removes nearly all caffeine unlike the more heavily processed versions.
