| I'll agree with the previous posters and make another suggestion too; are you sure your basal insulin is set correctly? If it isn't, it can mean that carb counting doesn't always make sense as you could well have the basal insulin dropping you too.
Once you've got your basal correct, you should then be able to find your rations and stick with them. It is not uncommon for your ratio to be higher at a particular time of day (e.g. many people have to give a little more insulin to cover carbs in the morning compared with later in the day but we're all different).
Other food for thought is this. When you give a bolus dose, you are trying to match the absorbtion profile of the insulin with the absorbtion profile of the food as closely as possible. You are doing this both in terms of the amount and also the speed. If you are using fast insulin and eating slow food, the insulin can get ahead of the food and you go hypo. Porridge is nice, slow release stuff. It may just be that your insulin is getting ahead of it. Try carb counting for the porridge, but perhaps add a small glass of orange juice (for which you'll also need insulin!). The orange juice will absorb quickly and raise your BG, holding off the hypo whilst the porridge gets in.
Good luck
