I also used to love "binge programming", a kind of hyper-focused/obsessed productive phase, but I totally agree that it gets exhausting with age and not sustainable in the long run. In fact, for me it creates occasional but fairly regular cases of burn-out. I'm still learning to become a more disciplined programmer. These days I'm trying to "stretch out the binge", so it's less extreme ups (and downs), rather a more long-term sustained focus and interest. I'm in no position to give advice, but part of your solution may be emotional and intellectual engagement with the process of programming, the tasks at hand and the problems to be solved. Also, as a programmer, you might enjoy building such a system as Scrum/XP/etc. that suits your situation best.
