I quit 2 years ago and I never felt better. I know it sounds strange but I read a book and I it was easy to quit. I strongly encourage everyone to do so because they can but they dont know that.
Congratulations, 2 years is a good time to be a non smoker. It took me 3 years to fully stop smoking, and I only managed it do it during the corona pandemic. It's been half a year now and I hope I can keep it up once we go back to normality.
