There is no problem with not leaving the house, you gotta do what keeps you sober, my first week I was soo shattered and tired that I didn't leave on my days off work, and when I was working just wanted to go home and stay in the house.
After a while though I think naturally you'll venture out in your own time, as withdrawal dies down and you start to feel healthier, you'll want to go out to appreciate the breeze and what life has to offer.
So yeap, relax, cling to SR . . . above all stay Sober!!
