Hi Mike; i'm sorry for your lay-off, that is hard to deal with, the stress it creates for your family too.
I think you are very smart to make a schedule for yourself and i hope your method of coping, keeping up with your field leads you to a better career, health benefits and fulfillment.
I can totally relate to "too much free time" as it can lure one towards the old way....i am still hesitant to take a day off from work because it reminds me of how I used to spend my time and my severe depression (which for me leads to drinking which exacerbates depression).
stay strong in your resolve and keep in touch.
