This doesn't really address your sponsor question, but there are regular cyber-meetings at:

AAOnline.net--Realtime Open AA Meetings on the Internet

If you're really having problems, you can just PM someone & have a private conversation.

In addition, there are live AA meetings anywhere you go (just like drunks ) -- just call information & ask for Central AA. Folks are usually more than friendly to out-of-towners & willing to have coffee if you're having the "urge." It only takes two people to have a meeting,

Also, don't forget, your regular sponsor is just a phone call away. Keep the faith.
