Thanks, good to hear that it can be controlled by diet alone, but I suppose I'll have to see how it goes. Confused about diet however, I see the logic of really cutting back on carbs and have already done this, but I don't want to eat fat as I have a lot of weight to lose, so at moment having fat free yogurt with some berries and nuts for breakfast, cheese sandwich on brown bread for lunch, and a meal in the evening mainly based around vegetables or salad.
