I have mine a bit boring - medium-strength, white and with no sugar (I used to have loads of sugar in mine, but when I got my first filling when I was 9, I stopped having sugar in it except in the most rare of occasions). But if I need a big punch in the face, I have it strong, black and sweet. Unless it's strong, it really doesn't do much, I really frink it because otherwise I can get a headache.
