I will answer your questions truthfully since you asked so nicely.

How many years has it been?

33 years. I have quit twice for 2 years each time and started back up again.

quit tomorrow, for good, with no struggle and no pain involved, would your answer be "yes" or "no"?

A part of me would say yes and a part of me would say no. I would be happiest to cut way back but without a wave of a magic wand I know even that is very difficult to do.
