Avoid drinks that has aspartame.

My friend, Valentyna, had told me months ago, not to drink flavor water that has aspartame, because it made her sick. I agree with her, but not just flavor water that would have aspartame, but also diet drinks. If you live (or traveling) Pennsylvania, New Jersey, Delaware, Maryland, Virginia, and Florida and you stop at Wawa, be careful with getting their diet drinks, because they do have aspartame. 

Recommend: Good Natured Crips

If I need to quit eating potato chips, I would choose Good Natured Crips. There are three flavors: Original (with Sea Salt), Cheddar Cheese, and Tuscan. My mother tried the Tuscan and she said it taste like ranch. But, it's a better alternative then chips and it has fewer calories.
