Cope Wintergreen isn't the cheap shit! Glad to hear you've just started your quit. Post roll for the day and commit to staying nicotine free for one more day. Then go back and do that the next day and the next..... The first week or so sucks a lot. The first 10 days or so sucks altogether. After about 13 days for me it started to suck less. It's still a constant struggle, but it's leveled out now, and I'm clear of the fog that you feel right now. It's worth it!
I have a similar story to yours, except I waited longer than you to kick the nic habit. Trust me, you want to stay off the nicotine. It ruins your life in the long run. Stick with the quit, own it, take one day at a time, and keep that shit out of your mouth.
We are all here working through our own personal quits together, from all over the world and from all walks of life. If you stick with your quit you will find a great supportive group here. You can do it, it is going to suck badly, but you can do it.
If you need anything shoot me a PM, I am online at weird times since I am a couple of time zones away, when most other people are sleeping.
