Argh...I can't get this bug off puzzling of my head! It's really weird, and so annoying, you know...I can't help thinking about puzzles all the time. It's like... when I see a word, I think of anagrams...when I see tiled floors, I think of sudoku on them...when I see a door, I look for loose bricks or business cards...

What's worse, this bug is heavily affecting my brain. For example, today I found that I had written the following on my notebook:

Text version:

This information technology simply never obeys the leaders. Nasal fluid begins a big ugly Indian mountain. A stupid person is the manager of codes. A locker is secure in heavy halogen. You are Eastern river in England.

Now I don't remember what it means, except that I've a feeling that the punctuations might be irrelevant. Maybe you people can help me out?
