Sweetchick, I am not an AA person but it doesn't make sense to me why diet and exercise should be against the rules. Both work wonders for physical and mental recovery.
AA is not a medical community.
Follow the doctor's orders.
If you have immediate non-judgemental support, SR is always here.
And more than a sponsor you need a PLAN to stay sober. The plan which will always be there doesn't matter what.
You have to be honest with yourself about what stays in your way to recovery.
I've never been to AA, never had a sponsor, but planning my actions ahead and making sobriety priority #1 worked.
Take care of yourself.
