Where's my high?

So I started running about 5 weeks ago with the help of the nifty Couch to 5K running app on my iphone (love it!) and I have yet to experience that fabled "runner's high". Instead I spend the entire time thinking "I'm going to vomit!". I'm so not a runner. The only payoff I've gotten is that when I remember to wear my heart rate monitor I can see how many calories I've burned during my half hour of agony; and as I'm dying the entire time with my heart ready to leap out of my chest, it's a lot. I'm serious, where is my freakin' runners high? I mean how long, how far and how fast do I have to run to get it? I really admire those people who say cheerfully, I run 5 miles a day. I don't know if I'll ever be one of those people. I'm up to running just under 2 miles and I have to psychic myself up days in advance of my proposed run. It's really pathetic. So, I ask if you've seen my runner's high, that you send it my way. Fast!
