2 weeks is awesome!! Yeah, you are definetly over the hump now, and hopefully feeling a lot better. Just remember that you will continue to have cravings here and there, and remind yourself of what you just went through whenever one of those cravings feels like it is too much to bear.
I had written a few diary entries during the worst of my withdrawal symptoms, and have re-read them on a couple of occasions when I tried to talk myself into using again. Seeing my barely legible handwriting, and reading my incoherent, rambling thoughts was enough to turn me off to the idea again.
Keep in touch with us if you ever need help or someone to talk to in the future - best wishes for continued sobriety!
