question: What is the name of the song about the after-effects of cocaine on the album that features the track "Waiting for the 7.18"?
context: Two songs, "Kreuzberg" and "I Still Remember", explore sexuality and homosexuality; the former is an account of promiscuity in the Berlin area of the same name, while the latter details an unrequited crush of a boy for his schoolmate.The leading track, "Song for Clay (Disappear Here)", was inspired by Less Than Zero, a novel by Bret Easton Ellis which depicts excessive hedonism and its effects on individuals. The song title references the protagonist Clay and a billboard in the book which displays the phrase "Disappear Here", while the action is relocated to Les Trois Garçons restaurant in Shoreditch, East London. "Waiting for the 7.18" provides an escapist counterpoint by mentioning a trip to Brighton following disillusionment with working life in the capital. The fifth song on A Weekend in the City, "Uniform", references London again and criticises the youth subculture in the area. It is directly inspired by Douglas Rushkoff's Merchants of Cool documentary, which details the corporate exploitation of popular culture by advertisement companies.Okereke read Guy Debord's The Society of the Spectacle and Henri Lefebvre's Critique of Everyday Life, works which analyse how people experience leisure in modern societies, and was inspired to pen several songs which detail the drug and drink culture present in a metropolis. "The Prayer" is based on drug use during nights out in clubs, while "On" specifies the effects and after-effects of cocaine. Okereke tried to treat the tracks as explanations of people's actions, rather than moralising tales; he has stated, "In a time when so many people feel they can't communicate or feel hemmed in, I can see the appeal of cocaine." "Sunday" details the morning-after hangover following a drunken and promiscuous night out, while "SRXT" takes the form of a suicide note following the loneliness and despair of hedonism in the metropolis. The album closer is named after Seroxat, a trade name for the antidepressant paroxetine, and was crafted following the suicide attempts of two of Okereke's friends after they left university in 2005.
