I do drink coffee, but not as stimulant to boost my productivity. The only time I drink coffee regularly is when I wake up. Otherwise I drink coffee only when I feel like wanting cup of it. Though usually its about 3 cups a day. I do drink also water from tap only and yellow tea.
I do not believe anything boosts your productivity, better than you yourself deciding to be more productive.
