Before university I was a moderate coffee drinker, maybe drinking a few cups a week. In university I would drink a lot more 10-15 cups a day especially nearing exams. I became concerned when my urine became noticably cloudy so I stopped cold turkey and didn’t drink any coffee for six months or so. Then one day I went to the “Chatter Box” coffee shop and had a coffee. It was then that I realized what a pyscho-active drug caffiene is. I was high and my eyeballs were vibrating.
The best coffee I had was in South India. Why? Because I was living less than 100 miles from the coffee plantations and I was friends with several plantation owners (even my surgeon who operated on my shoulder turned out to be a plantation owner). All along the street where I lived were warehouses full of green coffee beans (Arabica).
My friend, the coffee wholesaler, was shipping hundreds of tonnes of coffee from his plantation to Italy.
I had a laugh when an Indian friend of mine who often traveled to Italy told me how good the coffee was there. She thought Italy grew coffee and was surprised to find out that the “Italian coffee” she liked so much was probably grown in India a couple of hour’s drive from her home. 
Depsite the fact that S India grows fantastic coffee for some reason many Indians like a blend of 80% coffee and 20% chickory. They like the taste. I preferred 100% Arabica.
S Indians also have a distinct way of making coffee (with milk) as described in the video.
Since my wife is from the Balkans she taught me how to make Turkish style coffee as it was the Turks who introduced coffee to Europe. (It is said that when the Turkish siege of Vienna was lifted the Turks fled leaving a massive amount of coffee behind and thus Europe’s romance with coffee began).
She got me a traditional Balkan’s style coffee pot and I learned how to make it. This is very strong coffee. The Turks and Arabs like to add spices like cardamon to their coffee, so do I. (Cardamon also grows in S India.)
This video shows how to make basic Balkan/Turkish coffee.
I got into researching how different countries made coffee and stumbled on Vietnamese coffee which is one of my favorites especially in the summer for iced coffee. This link gives you an idea of what it is about.
The Vietnamese use condensed milk because at the time when they got into coffee under the French there were no dairy cows in Indo-China.
I made my own variations by mixing coco powder and spices into the condensed milk. My wife loved it.
But we stopped drinking coffee some time ago and don’t miss it.
As for the OP I would suggest, as others have, that you may want to get a medical opinion about your situation just to be on the safe side.
