Did quitting smoking make any difference for you?

I've smoked cigarettes steadily these past 2 years and for the past 9 months I've had significant discomfort in my right eye that typically lasts all day and even impacts my sleep.

I'm thinking of giving it up again, I was off for 4.5 years, I can quit again as I've went nearly half a decade without them and now it's been awful having no answers as to what caused the eye discomfort.

Cigarettes don't really do much good for anyone anyways and if I do I won't have to worry as much for all the health risks that are associated with smoking.
