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 to you, a very, very good life choice. I’m sure you are well aware of the long term risks of smoking. You’ve added years to your life probably by quitting, plus you won’t stink of smoke any more too
