You may want to try the Commit lozenges, which work like a pill that you tuck between your cheek and gum. It has been almost a year for me and I would not have made it through the first few months AND coaching in the spring without the lozenges.
It's almost been a year for me and the hardest part was elk camp this year, when everyone was dipping but me. It was also pretty rough during the spring, when all of my coaches chew.
