How fast does this work?

I’ve just started EMDR back after about a year’s break while I was planning my wedding. Last week I reprocessed memories involving my eating disorder (binge eating). It has been an issue that has plagued me my entire life, and is connecting to a lot of childhood memories of comments about my weight, forced diets, sexual abuse, etc. We did about 20 minutes of work, but during that time I had what we both felt was a break through moment. Since then, a little over a week now, I haven’t had the urge to emotionally eat or even over eat. The noise in my head surrounding food is sort of gone. As excited as I am about this, I’m nervous that this is a placebo effect? Am I making it up, or will this last? Any advice or anecdotes will be super appreciated. ❤️
