Off course specially with friends the taste of coffee will be different

No! Not wrong just know what you want

I don’t drink coffee. But I do have to have one 16oz bottle of Caffeine Free Diet Coke a Day. So go head and drink your coffee nothing wrong with that.

No, coffee is great
If you have trouble sleeping you may not want to drink it in the evening a lot

I like making a cup of coffee in the morning. Freshly brew. With French vanilla creamer.
