Hi Gemz,
Flushing down the bag was definitely a brave move and it’s a great start, I really think I know where are you coming from. Cocaine is the devil, believe you me. Have faith, you can overcome.
Not sure if it would help you but I have always felt that jotting down some affirmations in to your personal diary every morning can give you a perspective to make the right choice.
Good luck, friend. You can overcome.
