Take the syringes(pack one extra for this) with you, if they give you a problem at security asking you what it is, start to calmly explain that it is for your medical problem. When the agent asks what problem and were is your prescription, start to shake a little, then go in slight tremors, next drop to the ground and go into full blown convulsions. Start to yell, "I need my shots" then crawl to your pack were your juice is, grab the extra pin I said to pack and inject it right there, stop all convulsions. Calmly get up and explain what just happened to the agents and that you are sorry for forgetting your script and that you would be more then happy to contact your doctor and let them talk to him. The agents will be in such shock and backed up from the panic of the other onlookers they will probably let you go. Shit, man I'm just kidding, I would do what jay_steel said and just mail it to yourself!
