Tips:
- Get a big fan
- Have something to occupy your mind like a TV or iPod
- Don't give up too soon. It takes a few weeks of consistent use to learn to "enjoy" the trainer
- Build up gradually. 15 minutes the first time you use it should be fine.
- Have a good towel handy
- Protect the vulnerable components. Headsets and the bolt at the top of the steerer tube tend to corrode quickly due to sweat.
- Use the skewer that comes with the trainer. They tend to fit more snuggly which helps minimize the wobbles.
- Use your HRM. If you don't have one, buy one. It's a good tool for monitoring your intervals.

By the way, I used to use a ladder to mount my bike when it was on rollers, but I don't think you need to do that with a trainer since the bike is held firmly in place.
