Does anyone strictly follow a "5 days on, 2 days off" cycling schedule with Caffeine and L-Tyrosine, or does that just ruin your weekends?

I am trying to avoid building a massive tolerance where I need 400mg of caffeine just to feel normal. The idea of a weekend washout sounds good on paper for keeping receptor sensitivity high, but I find myself completely useless and lethargic on Saturdays. Is there a better tapering method that maintains baseline dopamine levels during the week without turning me into a zombie on my days off?
