If I want to get laid I forgoe the retro-hale. I retro-hale constantly. For me when I don't blow smoke out my nose a good floss, scrub, rinse is good enough. Retro-haling seems to have a lingering affect on bad breath. If you think about it you sinuses can't be thouroughly cleaned with a toothbrush, floss, or mouthwash. So the tobacco smell is constantly regenerating.
Abstinence is a cure too... If I hold out for a week, it wouldn't matter if I was a yellow bellied turd. She turns on me like a thirsty vampire. Problem solved!
