What you're experiencing now goes beyond desire or romanticizing the good parts, it's an obsession. Realizing you cannot stop thinking about it should be evidence enough it's not good for you. The thoughts you put in quotations in your last paragraph are your AV.. learning to identify and separate from those thoughts has made all the difference for me any many others here.
On another note, D122y's post is really so accurate. I haven't drank in 2 and a half years and my brain has started making its own natural feel good chemicals from normal everyday things again. So if I were to "forget" now (or at least see how it would be possible to) it's because I don't even think of drinking as being a part of or necessary to have a good time.
Your views will change over time and the obsession will loosen it's grip the less you give it any credence. But of course it's not going to happen overnight, so there's also a lot of wisdom in the "one day at a time" sentiment imo.
