I love coffee, but have almost completely stopped drinking it. At one point in college, I was drinking around 3 12-cup pots of coffee per day & around 120 oz of coke (I only slept 10 hours total Monday thru Friday). About 2 years ago, I went cold turkey with caffeine. Coffee was exacerbating persistent heartburn. Also, the effect from caffeine was gone, was effectively immune. 20 years of heavy caffeine use...after 2 years mostly clean, I get jitters from a single cup of coffee.
