Mo is absolutely correct.
There have not too many folks in recovery that I know that haven't had some pretty weird weeks before during and after their anniversary date. I personally use them as a positive to remind me of where I do not want to go back to.
Each year, it gets a little better, and the time span does get shorter. I remember my first anniversary I started getting 'crazy' with weird drinking and using dreams about 3 weeks before and they lasted until about 2 weeks after.
Now, with 31 years, just 6 days away, I had a drunk using dream last night, first one since last year at this time, rofl.
So, use those dreams as a 'positive' reminder of where you no longer want to be.
I have found that when I do get a drunk and/or using dream it is usually because I am under more than my normal 'stress.' Excessive stress will, every time, bring on a drunk using dream for me.
So smile, be thankful they are just dreams, and ENJOY your first anniversary.
