I stopped drinking coffee, because the good stuff was too expensive and the coffee at work tastes like battery acid. I drink Earl Grey tea with a pinch of sugar.
I'll drink coffee, but all it does is get me wired up 3 to 4 hours later. It never seems to have an immediate effect on me. Once I had 2 cups of coffee at Dennys and a handful of chocolate covered espresso beans half an hour after that. I went to sleep half an hour later, and 4 hours after passing out, woke up and couldn't sit still for the life of me. So drinking coffee in the morning is senseless. Drinking coffee after 10pm so that I can stay up late at night - now that's where it's at. Well, it used to be.... No more school, no more midterms, no more studying.
For me, it depends on the coffee. I can drink a couple of cups of regular office coffee on a workday and be perfectly fine. At home, I get my coffee from Central Market and grind it myself, so the quality is alot better, and I like dark roasts (French or Italian) so I get a little more wired. Every Sunday morning, if I am at home, I have a pot of coffee while reading the sunday Chron Fishwrap and NY Times. If you want a killer coffee buzz, have lunch or dinner at the Istanbul Grille, in the Village on Morningside near University, and have their Turkish coffee afterwards. It's next door to Little Woodrows and the Gingerman. You'll be buzzing a good long while. When I have lunch there on a workday, I'm amazed at how much I get done that afternoon!
Not sure about the boner effect, but yes, it seems that coffee sometimes seems to have that other effect!
My girl works at a coffee bar in Surrey, BC. Coffee makes her flirtatious. I get pretty wired sometimes. Like I'm ready for a fight by 6 am. Sometimes pack my baseball bat, just in case some ****er hits on my girl. Maybe I should switch to decaf?
I've been drinking coffee since before I can remember. Coffee doesn't keep me up. I can drink a cup of coffee and go to sleep for the night and not notice the difference. But, I still have a cup every morning because it's an integral part of my breakfast. I switched to decaf a while back. I had discovered that when I don't have coffee in the morning, I get a headache that will not go away until I wake up the next morning. If I drink a cup of coffee after the headache starts, it won't help. Tylenol won't help. I just went through the whole day with a headache. I didn't appreciate being addicted to caffeine so I quit. It was a miserable couple of days, but now I'm fine on decaf. Now, I feel just like I did on caffeine, except I don't get a headache when I skip.
Fresh coffee is one of my favorite scents, and I'm not alone. IIRC, there are studies which show that the smell of coffee is a mood enhancer.
