I was what most people would consider "high functioning"--important job, nice car, nice apartment, no credit problems, never arrested, no dramatic medical problems. Inside, I knew my drinking was getting worse and worse and it was all on the verge of imploding. I quit before things got to the point that many people get to, but trust me, it was progressing on the inside even if it wasn't showing yet on the outside. The illusion of "functioning" was about to go *poof*.
