You are doing incredibly well. My day four was spent curled up on the couch and eating my weight in junk food.
And yes x1,000,000 on thinking too much. I suspect we all do. At one point in human evolution, it probably kept us thriving while others got sat on by mastodons or eating by saber toothed tigers. Now? Not so much.
Keep on keeping on with your sober self!
Sending you a hug.
