medic alert bracelets

Hi to all, I was reading the national message boards and I read about some people buying a medic alert bracelet and having "no blind tubing and no NSAIDS on the bracelet. I believe I heard something mentioned at the last group meeting at Gerry House regarding NOT EVER having a tube inserted into your throat because of the wls. HOwever, I am not sure I understood everthing. Also I know what NSAIDS are and why should that be stated on a bracelet. What is wrong with NSAIDS? can anyone out there anwer this? Thanks Carol
