You want to deploy, and so do all the other Lt's. The shift work grind sucks, and dudes are looking for a way out. We just had a dude volunteer for a 179 doing TCN guard duty. My squadron has an unofficial policy of "everyone gets firsts before anyone gets seconds". I can't speak for other squadrons. Additionally, I've met exactly two pilots with two or more LRE deployments. As always: timing is everything and your mileage may vary. As far as "switching back to regular civilian life", I wouldn't worry about it ... you won't have time. Expect to work 50-70 hours a week. You'll have time to go to work, maybe hit the gym then get some sleep. Rinse and repeat.
