Just a thought about sponsors. They are only human. They don't have anymore power to get you sober than anyone else, and that's zero. A good sponsor is really a spiritual mentor who can show you, because they have done it themselves, how to work the steps and become connected to the God of your understanding who will solve all your problems. But you need to be willing.
Just an observation, but I have seen many posts critical of sponsors from sponsees who have slipped. I would bet that in the vast majority of cases, though, that the sponsor is still sober. Perhaps there is a little message here. If one gets involved and helps others (sponsors) one has a much better chance of staying sober.
