I use those two Pure Protein bars ( chocolate delux and choc peanut butter) as restricted, but limit them to 2-3 times a week. Since they are so high in protein I'll save them for days when I need an extra " shot" of protein. ( trip to the zoo with kids, performance day, etc. )
The other alt bars I use, also sparingly as a special treat, are the dark double chocolate and dark chocolate almond Zone bars. Those are the best and are the closest to IP double chocolate bars, which I really love. I keep them on hand as well. As you can see, I like my little dose of chocolate each day. It makes me happy and I've still been successful on the program.
The faux malted milk balls (Proto diet, I think) complete my " chocolate" needs.
