I have been doing some reading on PP, and you can drink alcohol, and caffeine. Also the starting carbs are 30. Just remember that you will burn off the alcohol cals, before anything else. I have been on a low carb diet, and lost 3 pounds in 4 days. But I don't feel good at all! I have no energy, nauseated, and have the runs I had to go off it today, because I am just to sick. But I will start back up tomorrow.
