Welcome to SR CrimsonKing. You will find a multitude of subforums here on many different recovery strategies, and general support for those at all stages of quitting/sobriety.
I was you to the T for many years ( drinking 3-5 beers a night, could quit for a day but wansn't happy about it, didn't drink in the AM, didn't miss work, etc. ). The last 3-4 years of my drinking though I started crossing some of those boundaries a bit. For example, needing beer to feel "normal" rather than just to relax. Also drinking mid-morning on the weekends. Anxiety creeping up too. There were others, but they really crept up on me without me knowing.
You are very fortunate and wise to want to nip this in the bud now before it becomes a larger issue, and you should be commended for it. Best of luck and let us know if there is any way we can help.
