Caffiene? I'm a coffee person. Now down to 3 cups/day from 4-6 cups/day. Grind my own so it's always fresh. I'm the only drinker in my house and found, even in 8 oz. bags, preground doesn't stay fresh long enough to finish the bag.
My absolute favorite brew used to be coffee shop Columbian Santos beans. When I was in Costa Rica, I fell in love with the local stuff. Supermarket coffee there is amazing. I prefer Cafe 1820 over Cafe Britt. If you want something more upscale there are single plantation Tarrazu's on the supermarket shelves as well. I'm not a big fan of "single origin" craft coffees. If I want something that tastes like grapefruit, I eat a fucking grapefruit.
I was unemployed this year and found, for cheap coffee, 8 O'Clock Coffee ain't half bad. As far as I'm concerned, it's the 100% Arabica value leader.
At home, if I want something that leans espresso, I use a Bialletti moka pot and if i want something milder, use an Aeropress . The Aeropress travels well.
Cocaine. I lived in Miami/Fort Lauderdale in the 80's. Cocaine was clean, cheap, and so plentiful, people used to give it away. Cocaine, fresh caught fish sandwiches and strippers. Life was good. When I started saving a bump so I could do my calculus homework on Sunday morning, I knew it was time to stop. Not the fish or the strippers....
