I think under 30g of carbs a day is too few. I think you're going to hurt your efforts in the long run because that will up your craving for "bad" carbs later in the day. You just need to eat the right carbs...fresh fruit, milk, whole grains, yogurt and starchy veg (potato, carrots, peas, corn) in the proper portions will do you good. I can send you more info via PM about my plan, as it is directed towards a "diabetic diet" but is actually what is recommended for everyone...though your partner may have to make some adjustments. What works for you won't necessarily work for him/her so the exact same plan is probably not a good idea. Are you each on the same plan listed above? How is it working for him/her?

I can totally relate to the diet soda syndrome. That was a hard one for me, too. But I went from several a day down to 1 or 2 a week so it is possible. I gave up my multiple cups of coffee a day at the same time so I was a cranky camper for awhile. I did this to relieve symptoms of GERD and now that I'm not eating the same amount of processed "white flour" and sugar foods I find I can have more coffee and not get the reflux. Still have to be careful, though.
