I'd also call myself an introvert, and the best productivity I get is when I dedicate a couple of days working from home with the rest in office. This allows me to get the bulk load of work done when I'm home and allow some social interaction with my colleagues the rest of the week, while still getting a decent amount of work done. It's consistently the same days every week that I work from home, so people I work with can have their expectations set on when I'll be around. Choosing random days does not really work well for this, as people get confused when I'm not there.
