sleep, overtime, and PR's

In the last month my lifts have increased substantially. I'm %100 certain its because I've been sleeping more. In the last month I've slept 8 hours a night. That's the first time I've been able to feel rested in 9 years. It shows in my lifting. In 4 weeks my front squat alone increased by almost 20 kilos (42 pounds). I've PR'd my snatch and clean and jerk and they felt easy. Friday we received 2 medical bills totaling $6700. And tonight my Suburban broke down. I'm back to working 12-16 hours a day, 6 days a week and not sleeping much. Looks like until i pay these bills off I'll be going back to getting slow weightlifting gains.
