My experience has been really similar to yours. I also was plagued by perfectionism, reworking things endlessly when I was younger. A beer makes it go away, commit to a design decision that is not necessarily ideal because it probably doesn't have to be ideal, and move forward. I find it helps me focus as it stops my mind from wandering off down infinite stacks over minor issues. Like caffeine though there's a certain precise narrow level where this happens and if you go over that level it doesn't work.
