Perhaps this is because over the years your mind has made a particular connection with smoking while at a hotel or even on a cruise because those places represent "fun times", usually a vacation and now your mind is afraid that cutting out the smoking will somehow diminish the "fun"? You'll be fine on your cruise because you have already identified this trigger and dealt with it as well. Start to think about all the improvements to your "fun time" when you get to that cruise next April You won't have to pack a carton of smokes and worry about having an extra lighter as a back up just in case. You won't be pushing your wife aside trying to get out the airport doors for that much needed smoke when you arrive at your cruise port by air. You won't have to huddle in that "smokers area" on the ship's deck and feed your addiction. Huddled there with so many other addicts all puffing away while non-smokers stroll by and casually look over at the poor addicted fools. No more travelling half the ship to get up to that smoker's place on deck first thing in the morning while others run the jogging path around you, getting their morning fix or oxygen and exercise.
Oh, sorry for blathering on and on about all the benefits you'll enjoy as a non smoker on your cruise in April. Now, what was it that you thought you might be missing out on?
Wantsit. You'll be just fine with all this by April. Just wanted to give you some things to focus on up till then. Yes. your mind will think about the old smoker you facing a new non smoking environment for the first time but you may just be surprised at how your quit strengthens, rather than weakens, when you go on that Caribbean Cruise. In fact; I'm so convinced of this I'm going to prove it to you. I'm going to go on a Caribbean Cruise for you and report back later on how it went If I'm gone for then next while, you'll know where I'm at. Doing research for you
