Having to take the carb blocker supplement when you eat a carb craver meal is sales baloney. If you have high BP I'm guessing you already watch your sodium intake, some of the CC meals can be higher in sodium (deli meat, commercial spaghetti sauce come to mind). I think you'll be fine.
Regarding your comment that the "carb craver" meals are a lot of what you choose for dinner, you may want to rethink that strategy - simply because your losses will be better if you limit your use of the high-starch meal choices. Once or twice a week, tops, is what I would suggest (any more than that and I find myself dealing with bigger carb cravings and then I fall off the wagon...LOL!

) It's not always fun, but I try to look it as a long-term change in my eating habits...
Hope that helps, some.
