Yes. Several times over the years. I do that for all that I consume--testing combinations and levels of consumption.

I appreciate your concern, and you are not wrong to query people exactly as you are, because most people aren't introspective about these matters. I hope people do read our exchange. But I and my spouse can assure you that I have thoroughly considered and tested this, and my four or five servings of alcohol a week does not have a negative effect on my physical, mental, or emotional health. That is only a statement about myself.
