See your sponsor as a teacher or adviser. Sponsors aren't parents or best friends ... it wouldn't work if they were. I hope you stay with her if this is the only problem you have with her. Part of getting sober is learning to accept others even when they don't do what we want.
I applaud the work you've put into staying sober. My emotions were very volatile (like PMS 24/7 in a full moon). It's tough but things do get better for all of us.
