I used too be very bored and that was terrible.
Now I am grouchy, and that is terrible.
I have been grouchy for 4 years I think.
From the day I started too quit nicotine.
Dopamine and serotonin supplements seem 2 help
I gave up cigs a good few years ago, switched to vaping then gave up vaping maybe 2/3 months ago. Still occasionally crave a smoke, not made me grouchy though, that only lasted a week!
