I've kept a journal for about 10 years now. Not quite everyday, but just about. Sometimes my daily entry is about the weather. Maybe a shopping list. Other times its what day sober I might be. Or I had a relapse and its day 1... all over again. Many times my emotions get jotted down, or even some rant I am on. I keep a small note book in my back pocket while at work. A rubberband keeps the covers from getting dog eared from going in and out of my pocket. I buy the in bulk at walmart for pennies and piece.
I used to keep a bigger notebook at home, but keeping one on my person at all times helps me through a lot of stuff. Almost like I can vent, but no one hears me.
