I just finished my 6th and 7th in two days and I've gotta ask. How do you guys smoke so much? After lighting my 7th I realized my jaw hurt and now that I'm done I swear the only time its been more sore was after my honeymoon weekend. My bottom left front tooth even wore a sore into the bottom part of the inside of my lip.
I realize I pack a fair bit more tightly (intentional) than more people, but still.
So like when I first started playing the guitar? (god that hurt like hell for months) Sooner or later those previously un-noticed and unused muscles build up their strength.
Usually in the vacinity of 5 to 6 most days for me, and lets say 8 to 9 on weekends.
I certainly hope I don't develop callouses on my tounge similar to those developed through 25 years of playing guitar/banjo/bass/mandolin/sitar, my wife would never kiss me again...
