Cool so you are watching what you eat to a degree. Monitoring carbs and/or sugars is a great start.
My problem is bread, rice, and potato's. Mixed with not eating regularly. There are times I may go 2-3 days with only maybe 1 real meal, then I may have 3 square meals every day for a week. Not good for the metabolism.
I can't find a low sugar drink that I care to drink consistently with a meal. Some folks like a beer with their dinner, I like soda, juice, or sweet tea... flavored seltzer tastes disgusting so that isn't an option.
