just try to relax and be yourself when you go to the docs, stressing about seeing the doc is not going to help, can your wife/girlfriend or someone else you trust go with you to the appointment for moral support?, if you dont want them to go in to the docs with you they can wait in th reception area whilst you go in, good luck in whatever you decide to do, by admitting you think you have a problem is half the battle, good luck and keep us informed
