大般涅槃經義記 2.28

2.28

自下第二約前良師能治之喻，請佛說法。「如來今當施我法藥」，請同良師與藥服也。「令我還吐煩惱酒」者，合服已吐。「而我未」下，彰己未同醒悟之人，徵請佛住。

From here below, the second part, applying the prior metaphor of the good physician being able to cure [the drunkard], requests that the Buddha preach the Dharma. 'The Tathāgata should now bestow on me the Dharma medicine' is a request corresponding to the good physician giving medicine to be taken. 'Causing me to vomit up the wine of the afflictions' matches taking [the medicine] and vomiting. The text from 'Yet I have not yet' downward reveals that one is not yet the same as an awakened person, and urgently requests that the Buddha remain.
