On looking back I think the milk was the killer, it is listed as a meal not a drink. I shouldn't have had it so near to mealtime. I don't know if I just overfilled the pouch or it was blocked but the pain was terrible, but the relief was instant. Anyway put it down as a good experience and learn from it. Bit cheesed off, its the first time I've thrown up, to be fair some people do it six seven times a day so I've been lucky. No more to eat that night, just concentrate on fluids.
