Congratulations on getting started! You really shouldn't let yourself get down if you have a bad week. I have had weeks where I have put on 2 pounds. Just take it day by day. If you have a bad week, start off on the right foot the next week.
I am a firm believer in the fact that you can eat out ANYWHERE on WW you just have to request that the waiter tell the kitchen make changes to the dishes. If I know where I'm going, I will look at the menu and modify whatever dish it is that I want. I know it may seem like a pain to ask them to change things, but most people don't mind and are very accommodating.
As for the traveling, take some fruit with you for sure. I would go through the WW recipes sections in here and see if there is anything that's easy to make you can throw in some tupper ware to take with you!
I think it's great that you have someone to talk to though!
Just remember, if you're having a rough week, there are ALWAYS people on 3FC here to support you!
Keep up the good work! I promise you'll get the hang of it, it'll just take some time like everything else does when you're new!
