I too did the hernia thing. it was pretty easy since I have actually had a hernia so I know all about it :thumbup: as far as telling people, I am your age as well and I have only told my close friends (like 3) and my family. My family is EXTREMELY supportive as are my friends that know. Everyone that sees me on a daily basis have even noticed the weight loss and I tell them that I am on Adkins (which isn't a lie) and I exercise daily (once again not a lie). I just don't tell them about the band. It's none of their business.
If you don't want to tell them, don't. If you do, great! It's all up to you. And keep coming here! Everyone here is a GREAT support system. It's nice to have someone to come talk to whenever
