I eat out at least once everyday. At restaurants just order what you want, they are great at making it for you. I think the hardest part was getting over being embarrassed of ordering special, but once you do it a million times it becomes no big deal. Also, have you tried the Josephs Flax seed pitas? I love these and keep one in a sandwich baggie in my purse. There are only three carbs in a whole pita and you can replace bread with it, stuff it with tuna or do a million other fun things. I also keep pumpkin seeds with me and (yes I really do this) if I know I'm going to have a salad I bring my walden farms blue cheese dressing. Yes, I have a huge purse but this is my life and I am not adding 5 carbs to a salad if I don't have to. My last secret weapon is sugar free gum, I love it! I buy a thing of the dentyne ice or whatever you like, and keep it with you. It comes in really handy when people (namely my husband) decide to eat chocolate, twizzlers or peanut butter cups around me. Just pop one in my mouth and I feel like I'm getting a treat too. They would be great on a trip too!
Okay I'm rambling but I hope I gave you some suggestions and CONGRATULATIONS on a great first week!
