Grapefruit is the biggest threat, but other fruits can interfere with drugs, too. Seville oranges, used to make marmalade, and limes contain the same active ingredients that cause the drug problems.
White Rabbit (Alice in Wonderland) The White Rabbit is a character from Lewis Carroll's 'Alice in Wonderland'. He serves the Queen of Hearts and is one of her most loyal servants. He also appears in DIsney's Alice in Wonderland and Tim Burton's Alice in Wonderland as an ally. Disney's Alice in Wonderland The White Rabbit was first shown walking peacefully without a care in the world, until he looks at his watch and realizes he is late for announcing the Queen of Hearts.
Notice that the white rabbit has a clock. There is metaphor here also, for to follow the white rabbit is not only a call for an important date, but it is a call to transcend time altogether. That date is with the end of time and the feeling that one is late for a date. You cannot be late when you are already there.
