You could try the "Pomodoro", a timer that has you focus for 25 minutes, followed by 5 minutes of relaxing or distracting yourself. Repeat. It assumes you are actively avoiding your work, and apparently it is a type of brain trick that has some support in brain science. It's advocated in the "Learning how to Learn" Coursera course, which uses brain science to teach learning strategies.

I recently stopped taking Adderall as therapy for ADHD. While it made me excellent at learning, the toll it took on my ability to feel pleasure and do anything not work related made it a double edged sword. Pomodoro has really helped me avoid distraction despite being much more distraction prone than I was on stimulant medication.
