Treadmills suck!

Like most people on here I prefer running outside, but due to weather sometimes I am forced inside and on a treadmill to do my training. And today I remembered I absolutely hate it! I usually complete all my long runs outside at a 8:30- 9 minute pace but when I get near a 9 minute pace on a treadmill I feel like I am going to fly off the back of the treadmill?! Is this a common problem for anyone else?
