Yes, I admit it, I am a drug addict 
That is, if you consider alcohol and caffene drugs. My body is very sensitive to both of these substances, but they can also be very useful for me in certain situations. Though sometimes I wonder if it is the substance itself that is lending me these benefits, or my own perceptions (like a placebo) that cause it.
In the morning, I will have a single cup of coffee. Only one cup is all I need. The cup of joe doesn’t so much get me buzzed as it wakes me up faster. See, I take a long time to completely wake up. So long, I often get up earlier just so I will have more time to ‘wake up’ before work/school. Coffee reduces the amount of time it takes me to wake up. But it doesn’t make me any more awake past that point. However, I noticed that when I have a cup of coffee, I am much more motivated and creative- I look forward to going to school/getting things done. This seems like a powerful tool, but I’m always worried I’d use it as a crutch- that I’m not a productive person, its just the coffee :smack:
As many people have already discovered, alcohol is a great social lubricant. A few drinks is a great way to smooth over awkward get-togethers. I find I am much more outgoing after I have a few drinks, and this often works in my favor, in terms of social networking and whatnot. Traditionally, my mom’s family would always go out to dinner on birthdays. I wasn’t that thrilled about the whole thing because they take forever and a day to finish eating (I eat pretty fast). But when I was old enough to drink, I had a great time, and really started enjoying the quality time. I also really enjoy having a good beer after work, it is one of the most relaxing things in the world.
