Hi. I was a binge-eater for 30 years, ended up having to have weight loss surgery. I quickly turned to drinking when food was no longer an option.
I've been very worried that once I quit drinking, I would turn to something else. I don't really have an answer for you (I've asked the same question in SR before). I do find that I need to fill my free time with lots of different activities. I could easily start obsessing over SR, AA, exercise, shopping... Whatever. I need to diversify.
I do crave my sugar though! I buy candy in copious amounts. I'm doing this thing I did with my kids, I portion it out in smaller amounts in ziplock bags, and I'm allowed one bag a day.
