I had quit for a few years and then started back on business trips and now after 7 years of full time. I flushed a brand new can on June 11th and said enough. Some rough the last week but holding strong. I stopped at 7-11 and the dude just reached back and grabbed a can and I said no thanks. I told him I quit and he said that's good. Dentist appointment on Friday. Sore mouth and throat. I got this.
