You could also replace the splenda with stevia. Stevia is an herb and is very healthy. It is not an artificial sweetener and therefore is far less likely to have a toxic/negative impact. In fact, it is reported to balance blood sugar levels which is a plus.
It is VERY sweet so you need to only use very little. I like the brand by Herbal Select. You can find it in health stores and many grocery stores who have a natural health section will also carry it. I bake with it all the time. I have a flax muffin recipe I use it in and it works really well.
You guys probably already are aware of this, but just a reminder that drinking a good full glass of water with or close to a high fibre meal is important and will also amplify that wonderful 'eureka' effect all the more.
