I've eaten just pizza toppings too. I imagine it's fine, but you might want to fill up on a little salad or something as well, as it took a lot of topping to satisfy my hunger.

A lot of people say the digestible carb thing is crap. What I've learned by reading others' experiences is that it's truly an individual thing. So, you just have to see how it treats you. I also make my own Splenda jello for a taste of something sweet.

Those supplements sound lovely. You seem to know what's up, so I think you'll start to feel better with that good dose of vitamins.

Happy low-carbing!
