Since you didn't like my comical response; here is my librarian response:
Try eating a lot of green, leafy vegetables. Parsley is great. Celery could benefit. Greens like collard or turnip or mustard or spinach or alfalfa sprouts, etc. can go a long ways towards handling the odor. Also, you may want to try some fruits like lemon or lime.
Eat some of those with the rind to help rinse out the system. Oatmeal or oats could help somewhat. Raw potato may be of benefit. [Edit: certain greens mentioned above can possibly help alleviate symptoms of odoriferous garlic discharge but at a cost of yet another unpleasant gastrointestinal discharge. Drinking water and working up a sweat will only intensify the garlic discharge however it will probably help to run it's course more quickly! ] End of Edit.
I should mention that the probiotics of fresh vegetables alone can help a person. In other words, when eating fresh greens, you can obtain beneficial microbes in a way that is similar to yogurt's beneficial microbes.
Working up a sweat shortly after eating
garlic can help expedite it through your system. [Edit: Drinking a glass of Milk was also suggested in another topic from another website however, if you were lactose intolerant this wouldn't be a viable option.] End of Edit.
Different people have different body types and eating habits and systems, so you will want to experiment with what works well for you.

Of course I'd go with Junior's suggestion of Jack in the Black/Wrigley's but then again, I keep a good safe distance from Junior just on principle! Hope this adds to your list of trials!
