I wondered what I would do, also.....but the "cat was out of the bag" when coworkers heard me asking another coworker, who had a band done last year, what the process was.... since then I have told my manager, other coworkers, my doctor, my chiro, and finally, today, my daughter. Everyone has been very supportive...my doc said I was very healthy and an IDEAL candidate....
point: there will probably be much more support than you think. My "band" coworkers told me they were proud of me for "admitting you need help"....and I feel a lot more empowered now that I made the decision to go ahead with the band. All the best to YOU!
