Personally, I would go for the inpatient option, reason being, even if nothing too bad would happen when I was withdrawing, i'd always convince myself that it was about to. Having someone there who is trained to discuss fears with etc, would be a God-send.
Luckily, nothing bad ever did happen and I don't plan on ever drinking again, so it's not likely to now.
Take the pressure off yourself - go for the inpatient option
