I'd just say watch yourself. Be confident, but don't be complacent.
After end of last month, I thought I'd beaten it forever. Turns out I was wrong. After 4 months of doing so, so well, staying sober apart from a couple of slip ups in Feb and one in Jan, I went to Chiang Mai to celebrate Songkran in Chiang Mai (Thai new year) - and fell off the wagon spectacularly. As in, big time. Felt like being back at square one again.
I dont think it ever goes away, really - as others have said, it just kinda becomes quiet.
