You idea of waiting until March break is not a bad one. That would give you at least a week or so to get through the worst of the symptoms like brain fog. Using NRT's is up to you. If you think they may help, no harm in trying them for the first while at least. You can always stop if they're not doing you any good. Just don't expect them to make quitting easy; it won't be no matter what you do. They may in fact take the edge off the withdrawals for you at least initially
Yes you'll probably take out your anxiety and frustration on the ones you care most for. Realize that and perhaps give them a heads up or even apologize in advance? Do your venting here on the train. No one here's gonna think any less of you cuz we were all the same at some point - we can take it! Being short tempered and feeling like I wanted to explode at times was the quit symptom that lasted the longest for me.
Remember, quitting is a marathon, not a sprint and you want to take it just one day at a time otherwise, it can get overwhelming for you. Wake up each day and commit to not smoking just for today! Then, rinse and repeat tomorrow. Small bites are easier to digest rather than large ones! And don't over complicate things. There's only one rule - don't smoke; not even one puff!
We all believe you CAN do it!
