I'm here right now (at CFLRS) and I don't find it too bad. I'm on RFT, and we work out the whole day, so by the time 2300 rolls around, we're dead, and just feel lucky to have somewhere to fall onto. The waking up at 0500 you'll get used to quickly, after 2 weeks of being here, I'm already getting up at 0500 whether I need to be or not, out of habbit.
One thing's for sure, you'll never be bored, there's always something that you need to do. even in your "off time" you need to prepare for inspection etc.
