I’ve nailed some stomach trouble I’ve had down to coffee.  It’s disappointing, cause I like coffee.  I’ve been trying to substitute sleep for coffee over the last month or so.  A few days ago I bought this coffee.  Instant.  Made me feel a bit old to be honest.  It’s not like the real thing(I know my father in law wouldn’t find it acceptable), but close, and it seems to be easier on the stomach… so we’ll go with that for a while.
