I was feeling the same way the other day and relapsed
I was at 59 days and just like you were saying I was more energetic clear motivated and just felt totally comfortable and secure in my sobriety and so I was invited to a place that I used to drink at with my friend who still drinks and once I got the thought in my head it was basically an obsession at that point and after I let the obsession fester for a couple days it's like I had no choice but to just take the first drink. No amount of meetings or anything could bring me off the ledge.
It really is an obsession. It is insanity. Trust me if you drink you will regret it. It will not be as fun and relaxing as it sounds.
