I agree with ross and loony bin, don’t take any breaks, when i got my first part of my ribs i sat for an hour and took a smoke break, then wen i went back to finish i only lasted about another 35-45 minutes before i had to tell him to reschedule. but i went back to finish it and it took another 1.5 hours to finish but i would of been able to sit through the pain much longer by not taking breaks. and bringing something like a dvd player, movie, etc helps a lot. as like you, i am going to be adding to my ribs in october and i am really NOT looking forward to the pain but it is worth it in the end

another thing i do, only because that spot is so bad, i wake up early that day, have a good breakfast, and literally pump myself up as if i am a linebacker in the NFL on gameday, ya know just get your mind set to deal with the pain, seems to help me a little bit
