Wow i could have wrote that last year! I did that for 5 months and it was horrible, for me, after the initial elation of stopping drinking had worn off, i was always smiling and everything is great kind of thing but whenever i was walking by myself, alone at home, in a lift...anywhere alone...i would just be looking down at the floor staring into space...just sucked!
I went to AA and worked the steps and got my spiritual awakening, it really has given me the ability to live a life now and the present and future do not look bleak anymore and i have cleared up the past...i would recommend it to you very strongly but i had to do the initial work of the steps to the best of my ability with a sponsor:-)
