p.s. One thing I don't see mentioned in the earlier thread is to be wary of alcohol. Like caffein, it's a diuretic, so it dehydrates you. Also, it's a vaso-dilator -- it expands your blood vessels. So if you're already having some internal bleeding - and UC will often give some intestinal bleeding - and then you have a drink, you may suddenly bleed a LOT. Once I was travelling, had a lovely dinner in a fancy restaurant (I still remember the Jerusalem artichoke soup with salmon roe ) and had one glass of wine with the meal. Late that night I woke up in the hotel bed soaked in blood. A bit scary, but I figured out what had happened and was feeling ok by the time I woke up. But it was also very embarrassing. I stripped the linens off the bed and hand-washed them in cold water in the shower, then left a big tip for the maid.
