No bad stomach pain. Just a little. No headache. So far so good. 202 pounds. Here's what I've been doing, foodwise: as usual, trying to stay between 2000 and 2500 calories - for me, my height, my activity, this is reasonable and manageable. I eat small meals, about 500 calories each, including carbs & protein and little fat, generally. As usual, include a lot of fiber (it pretty much happens naturally with the many fresh fruits and veggies I eat). Try not to eat any meals of just carbs and fat. By having several small meals and thinking of them each as meals, I don't feel so deprived. I know another one is just around the corner. Also, I try to load up on carbs with a hint of protein within 15 minutes of a workout. And I try to quit eating in the evening. That's the deal for now, and it seems to work, to help me lose very gradually.
