Hi Roger, know how your wife feels, I picked the little bugger up in Africa months ago about July and the symptoms get worse as u go, to the point where I simply stopped eating and lost over a stone, and I'm only little anyway. For me it came on so gradually, I forgot what normal was! Basically the way I experienced it, it became like having an allergic reaction to any food I ate, always stomach cramps, stomach turning, so tired constantly, the only time I felt ok was when I was hungry and weak. It sucks as it's hard to get the tests, my blood test was normal, it doesn't show, and doctors thought I was stressed.. which I clearly wasn't, until people starting asking if I was anorexic.. which I wasn't so I went to a different doctor. The antibiotics are great.. well actually awful, I was throwing up most nights on the first lot metronisazole whilst trying to complete coursework, but once u start the second, u feel practically normal really fast, oh but just make sure it's gone, I'm going back tomorrow cuz even though the after-test was normal, I know it's still there and getting worse again

hope that's some help, if ya need anything else, I've had the nasty thing so long I know it pretty well now! Jen
