I expect you are back from your trip by now and ,trust you enjoyed your freedom. I have only just read your post and it really rings a bell with me. Not smoking when away from home on ferries or planes will be so much more enjoyable.
Wee Done!!! Keep feeling good and proud...you deserve it! Those feelings will fight any negativity that sneaks up on you. You are both doing so well! Keep up the rewards too....you deserve those as well!
