I need a great!! speed workout.

I'm a Speed Freak through and through. :D Uh, no, not that kind of Speed. I'm talking about 25 and 50 meter freestyle type of speed. There is nothing I want more than a low, low 20 second 50 SCM. Any good workouts? Just the idea of swimmng anything beyond 100m makes me ill. All of you long distance swimmers are truely nuts. You should seek medical help. I've only trained/ swimmed competatively for 2 months and I know my lungs are way out of shape. Maybe that's why I like the shorter distances. Currently my best 25m time is 11.3 sec and my best 50 SCM is 26 sec. Danke
