I think 'full' is subjective. I don't miss being 'full' because that meant bloated, gassy, wishing I hadn't eaten so much, because now I feel like heck. I usually feel fullER (though not stuffed) about 20 minutes after I eat. I guess it's true that it takes 15-30 minutes for your brain to get the 'full' message.

Do you eat large meals three times a day, or smaller ones more often? Perhaps you need to eat more frequently... one thing I don't like about Protein Power is how they list protein requirements by the meal, instead of by the whole day. I could rarely eat 27 g of protein in one meal.
