Sentence examples for drink by from inspiring English sources

I'm not entirely sure what you mean by "drink by" in this context.
"Drink by" could potentially refer to a time or deadline for finishing a drink, such as "please drink your water by noon." It could also be used in a sentence like "I was told to drink by the river." In this case, "by" is indicating the location or proximity of the drinking activity. In written English, "drink by" may be grammatically correct, but it is not a commonly used phrase. It is more common to use "drink at" or "drink near" to indicate the location of the drinking activity. Example: "Let's meet at the bar to grab a drink." or "I like to sit near the window when I drink my morning coffee." I hope this helps clarify the usage of "drink by."
