Congrats on moving past the urge Midnight.
I too have recently thought about that "reward drink". Recently I began working everyday (I work from home) again. I hadn't experienced an urge in quite some time (I'm almost 7 months sober)...until I started my old routine. When I was still drinking, I would always start drinking as soon as my work was completed. Once I began working again, that same ol' urge to reward myself after a productive day returned. It was so strange because I hadn't felt the need to drink for quite some time.
Luckily, I didn't succumb to the new urges. Instead, I changed my "plan"/routine and began working out after work, instead of working out first thing in the morning, as I had been doing for the last 6 months. It worked! Now I look forward to my afternoon workout, instead of a drink!
