Congratulations on your new day one, and new sober journey. When will you be going along to AA?
If you enjoy reading, along with The Big Book, I would def recommend reading (or rereading) Living Sober. Also, The 12 Steps and 12 Traditions is, I think, fantastic for getting your head round the different steps. (Available to read online for free).
Alcoholics Anonymous : Twelve Steps and Twelve Traditions
I also found listening to AA speaker recordings great for keeping me focussed and in 'recovery mode'. There are loads here...
5500+ AA Speaker Tapes - Organized & Mobile-Friendly!
and also on youtube if you search for 'AA speaker' and whatever you're struggling with.
Onwards and upwards, eh x
