Just wondering here, but wouldn't you get the same result if you ate a small salad with oil and vinegar?....or ate some cooked kale with vinegar sprinkled over it? I've sliced up some cucumbers, and put them on a plate and covered them with a 50-50 mixture of vinegar and water. I've heard some smokers call these cucumbers phlegm busters, since it helps clear the throat. The cucumbers can be kept in the refrigerator in a tupperware container with enough vinegar/water solution to keep them floating in it. Just shake it all up when you want to eat some before bed.
Eating any of the above would give you the vinegar, plus it would be more palatable. It would also add to your carb intake a bit, so that might be a concern.
