It takes time.
How many years had you previously thought about having a drink all day only to have drinks all day? It becomes ingrained in you.
It does slowly dissipate, for me it took a bit over a year to get rid of that habitual thought process. These days if I think about a drink it's a passing moment here or there and I don't actually put much thought into it.
The only time my AV starts squeaking is if I'm stressed out and feeling like raging at something. I try to just calm myself down instead. Drinks never work well when angry at something.
