Stay strong, make sure you tell your sponsor, otherwise it's just that alcoholic voice getting louder! You now see the signs leading up to your relapse - not telling your sponsor is another sign that things could get worse.
I'm sorry you slipped up, but the lessons you learnt in your two months are still valid. From my personal experience I don't know anyone who managed to quit first go (or even second or third go!), so don't beat yourself up too much, but don't let yourself off too easy either.
Find the happy medium, give your sponsor a call, and jump back on the wagon
