Hey Expat, tried that Clif bar on Sunday arvo. Looks damned ugly, tastes OK, filled a hole. But I mustn't have had enuf water with it coz I got killer cramps a little later. I thought a little alien was gonna pop outta my abdomen they were so bad! More water (about a buckets worth!) fixed the problem, but took a while.
I think I'll stick to bananas and bland-bars (they come in three flavours of bland) just to be on the safe side.
BTW, how much for the patch thingies?
