Welcome to SR. What you are doing is very difficult. I was originally more of a white powder user and I found that quitting was about having a very good reason. What's your good reason? I also spend my entire life dealing with writing and I believe deeply that we believe what we write. So write down your reasons. When you want to do a line, write down why. But before you decide--answer that with why you shouldn't. For me it's day six quitting alcohol. My friends will go out tonight. I will not. It will be sad. Here is my practice:
I would like to go to the bar and have a drink and laugh with every.
Why not? Because I need to feel good tomorrow to visit my grandchildren.
I would like to have a glass of red wine and let it wash over me.
Why not? Because I know full well I cannot stop at one.
Write here and never assume no one will answer. They will. It's amazing.
