Have you tried breaking up any of your usual patterns? It may be hard to do with schedules and workload, but just exercising 2 or 3 times a week can make a huge difference. I've found that 90 minutes of exercise per session is its own drug.
I'm trying to get back into it anyway.
I even got to the point where I'm exercising 5 days a week and so I go out binge drinking on the weekends much, much less.
