I'd concur that it is pretty much up to you to decide what is a relapse and what isn't.
On the other hand, as people trying to recover from addiction, we can sometimes convince ourselves that something is okay when it isn't, which can be a slippery slope.
I haven't had an intoxicant in one week, this time (yay me bec the first week is often the hardest), but I am on prescribed escitalopram 10mg, quietapine 100mg, and today I had 3 cups of coffee which, for where I'm at now, was too much.
But I don't count those things as being not-sober.
Nor did i count the time I was injured and had to have an IV opiate at the hospital.
Anyway, welcome to the BL H&R subforum and best of luck, it gets better.
