Food and drink appear to be in different categories. At least in terms of meds. Just in case, smoke is also not food. So neither a cigar nor a few cigarettes count for food. A good cabernet, even if described as meaty and earthy, just isn't food.
Food means something solid.
Like some starch. And even while drinking, there might be some food options that still have some appeal. Perhaps a bag of pretzels, chips. Even beef jerky could do it. Perhaps if instead you do eat earlier that night, you might take the meds then.
