My uni room stinks. Mostly of smoke, I think, but also of sweat due to the erratic heating system and meals because I eat meals in it. How do I make it smell good again? I've had the window open all day to no avail.

Rising DiS star "atbay" has suggested I buy some 'erbs like basil, which I have done. Time will tell whether they have been effective.

Any other suggestions?
