Change of Environment
I've worked over 6 different locations in the last 2 months, and in each location my routine changed. Sometimes due to timezone changes, and sometimes due to what was available for breakfast.

If you want to change your habits, shift your environment. Forcibly break your norms by making them inconvenient or impossible. You'll no doubt find frustration, but maybe you'll find new grooves which feel better.

Regardless what happens, you might be forced to think a little more about why your habits are what they are.
