blquit, I'm new at giving advice on this site, but since I have made it to 180+ days nicotine free, I now have some credibility to share some insight.
That is great that you have support from friends to quit, and there are a lot of helpful people here to guide you to freedom.
Only by being committed 100% to quitting will you be able to stay quit, whether you are a can every few days (you), or 2 cans of CopeLC each day (me). Addiction is the same regardless of the amount.
If you leave any reservation or excuses available to continue dipping, subconsciously you will be tested.
WARNING: Going after a quit around the end of a college semester, is especially challenging. You will feel the fog, even with a can every few days. Just a heads up. Good luck!
