I'm doing the same - abstaining from life for a bit. Here's how it breaks down: reading (self-help/recovery books), sleeping, internet (SR mainly), solitaire for some serious mind-numbing and DVDs.
My problem is not feeling guilty about it (I've made a lifestyle out of guilt) and not feeling like I should do 'worthy' things with the time (like clean the apartment). My cats are fed and cuddled and my dishes are done. That's all I can manage.
Outside? Shops and doctor and that's it.
Next challenge (but not yet): walking in the park.
Good luck.
