This sounds a lot like me. After my inefficiency even drove me to a burnout. I redesigned my life to something that works for me. As software developer there are always more passive options that allow you to set your own schedule. It also allows to work remotely what keeps my head out of further depressive holes (not exactly ADD but often linked) by beeing able to experience new things and environments regularly.

It's not perfect but it works better for me than any medication / job combination I tried so far.
