aw i hope you feel better soon scarlet, just concentrate on getting well huni, the cards can wait for a while cant they, that amount sounds ok to me.
emm n emm, on mine ive got '' rny gastric bypass, no nsaids, no sugar, no blind ng tube, salford royal hosp. complex spinal con. and hospital number'' mine is just a stainless steel dog tag, and the company i got it from engraved for me, they also send a card, and a little open up card, where you can put more info, and then put it in your purse/handbag. there is also a tiny red st christopher type thing on the tag, with the medical logo on. oh and it has my name on other side of it. i got mine a few weeks after my op, and a nurse on here told us what to put, as she worked in a and e, and had one herself.
hope this helps, oh i got mine from 'universal medical' but there are a few others out there, just google it
