You are not bad, far from it. You are doing very well, judging by your losses so far.
I have heard that sometimes people do have an occasional very hungry day and find that they have an extra pack (much better than having off-limits food), then perhaps find the next day a breeze and have 2, so it all evens out. Or they have a small supply of extra foodpacks for days when they need a bit more - after all, one extra foodpack is a very low carb and low calorie addition to your daily intake. But I would imagine that this is not good to reduce to 2 on a regular basis as you could get weak.
But quite a few of us do SS + and the losses are very similar to SS. Perhaps you would like to consider this, its a popular and enjoyable way of following CD in my opinion.
Don't worry, keep up the good work and best of luck! x
