First, congrats on your decision and welcome.
Second, sorry to hear about your paw-in-law.
Third, you must really love pain? Three days is the worst of it. Day 4 (generally) is when the pain starts to subside just a bit, and you start realize that quitting can be done. If you reintroduce nicotine at anytime, you get to start over.
Be tough. You can make it. Its not that bad for that long.
