It was either Rava or Rabbah (I keep forgetting which) who used to eat fat meat and wine which he said opened up his mind to learn Torah.
If he had lived during the time of the Rambam and if they lived near each other and talked to each other regularly, do you think the Rambam would have told him he was forbidden from eating the fat meat and wine?
Even if the Rambam had said that, do you think Rava or Rabbah (I keep forgetting which), would have stopped….Especially if it meant his Torah study would have suffered as a result?
