Wouldn't you also have have the grapefruit at about the same time everyday, and take the affected drugs at the same time everyday? From what I've read there are two ways grapefruit interferes with medication. 1. For some drugs, such as statins, those drugs are broken down by certain enzymes. Grapefruit interferes with those enzymes, resulting in more of the drug circulating in your body. In effect it is as if you took a larger does of the drug. 2. For some drugs, fexofenadine is a common example, those drugs rely on certain transporters that move the drug into cells. Grapefruit interferes with those transporters, resulting in less of the drug reaching cells. In effect it is as if you took a smaller dose of the drug. It sounds like this would be sensitive to timing.
