I've definitely experienced this. I've isolated so much in the last few years that it seems worse now that I'm making an attempt to not isolate so much. I'm simply trusting that it will get better as I get more adjusted.
Oh, and crabbiness is to be expected. It's in the Big Book. We get irritable when we abstain. I'm no expert - still a newb to all this - but I interpret it as a reason to work the 12 steps as a means to recover instead of just be an irritable dry drunk with untreated alcoholism.
Best,
