It's a start. I'd rather see oats or something natural vs. special K crackers. Also, don't be afraid to use low-fat cottage cheese. A bit of fat is good for you (and vital!).
It is what it is. Just because you've started doesn't mean you can't stop now. But again, it sounds like you want to see it through to the end so this is the last i'll mention of it.
PWO is an ideal time for carbs, so yea... I'd say you've been selling yourself short.
Which Kashi cereal are you using? I've only seen one that is decent for what we're trying to accomplish... and note I said "decent"; not ideal.
Although carbs are protein/muscle sparing, it's not just about carbs. It's about total calories, and protein intake as well. First - what is your PCT protocol?
