Thanks for the good advice, esp. detail from awac. For starters, I've cut out the desserts and sugary snacks, and I ditched the sodas as well. I sampled the Isagenix, but see it as expensive and far from a long-term solution.
After just a week, I can say that the sugar cravings are way down and I'm feeling better. It's been tough eating the 6 oz. sirloin with a salad vs. the cheeseburger and fries, but I'm pretty motivated. I'm working hard on portion control and healthy snacks in between meals. I've found it takes planning with our schedules, but other threads on here helped with that. Will report back.
