Re: I really feel like giving up!
I was not a soda addict, but a big booze drinker before I got pregnant. I relied on Izzes, which are soda-like fruit juice drinks (no refined sugars -- which aren't helping you or baby), throughout my pregnancy and now when I'm nursing as a substitute for having a beer or glass of wine in my hand at dinner or when socializing. As for dairy, there are SOOOO many things you can substitute. Get a good vegan cookbook or look up some cheese substitutes (Daiya is a popular one now). It's hard when you're nursing, because you're so hungry and look to comfort foods. My baby wasn't bothered by dairy, but I'm not a big dairy eater in general; however, I craved cheese all the time. I tried to limit eating it to those times when I was out to dinner and couldn't substitute. I think if you substitute for most of your milk and ice cream type foods (higher lactose), some occasional cheese might not bother the baby.
