As for me, I was scared about phase 2 as well. My DH's grandfather passed away and we traveled a couple hundred miles to WI to go to his funeral on the day that Phase 2 started. I didn't do the best because I had a poor number of choices, but I brought a lot of food with me and did the best I could. When I got back, I was at three fruits a day and two starches. I found that I did not lose anymore weight on this, so I immediately took away a starch and a fruit. I then took away another fruit and started losing again, so I am at one starch and one fruit. If you don't panic about the pounds you might gain in the process, you can really find out what works for you.
As for carbs, having never been diabetic or on Atkins, I never count them or pay much attention to them. I do look at low carb products if they jive with SBD, like the low carb catsup (which is also low sugar) and some bread products. But I will choose a high carb bread that is whole wheat over an "enriched wheat flour" bread with low carbs. I'm very conscious of what they are putting in to lower the carbs and whether those replacements are SBD friendly.
As for chocolate, we are allowed semi sweet or dark chocolate. Ruth thinks 1/2 oz of chocolate makes a good serving. I, who used to have to have chocolate every day or I would eat the house, find myself pretty much free of such real cravings. But we have the chocolate in the house, and twice I have indulged, both times with strawberries in hopes that the fiber in the berries will help reduce the amount of sugar in my blood. I have had very few, if any, cravings as a result and no change in the amount of weight lost. I eat WW pasta (have no idea how many carbs it has) and WW bread, couscous, brown rice, and other whole grains. They are awesome and satisfy me without the need to go off plan. I do miss potatoes, but that craving is fading.
I hope that others can have the same kind of satisfaction that I am finding eating this way. It really helps me so much! I must say that the couple times I had ice cream sandwiches made with sugar alcohols (Slender Pies), I had huge reactions in terms of blood sugar. I felt woozy and about to faint, terribly weak in the knees and horrible afterwards. I stopped eating them right away and threw the rest of the package in the trash (much to DH's dismay). I'm definitely not fond of them. But not everyone reacts that way.
Anyways, that's my $0.02!
