Jerry this may have been a side effect of the radiation. The tingly feeling as if drinking a 7Up may have been caused by the coffee hitting raw inflamed skin in your throat. I have an uncle who experienced this exact same thing. Give your body time to heal and you may find your coffee taste didn’t change much. I know that the hotter the coffee is the more likely you will get the 7UP feeling. Try cooling your coffee down a tad before drinking yo see if this helps.
Again, it's the caffeine working here. Your recommended maximum amount of caffeine is 400 milligrams, roughly the amount that you’ll get from 4 cups of coffee. If you’re caffeine-sensitive, be careful with coffee. You are probably already aware what amount and what kind of coffee suits, or doesn't suit you. The amount of caffeine that is safe for human consumption is actually written in our DNA.
Possibly the most popular type of coffee in the world, a cappuccino consists of three layers (kind of like a cake). The first is a shot of espresso, then a shot of steamed milk, and finally the barista adds a layer of frothed, foamy milk. This final layer can also be topped with chocolate shavings or powder. Traditionally, Italians would consume this type of coffee at breakfast.
To make an espresso, shoot boiling water under high pressure through finely ground up coffee beans and then pour into a tiny mug. Sounds simple right? Well, it’s surprisingly difficult to master. Espressos are the purest coffee experience you can get, and while they’re not for everyone, it can be a truly singular drinking experience when you find a good brew.
People who drink four or more cups of black coffee a day (24+ oz.) have a 20% lower chance of becoming depressed, and are over 50% less likely to commit suicide. Drinking coffee is literally a life saver, and something I wish more people would do more often for this specific reason. If you know someone struggling with depression, taking them out for a cup of coffee here and there can make all the difference.
So I’m doing Keto and intermittent fasting so I’m trying to make the switch. I’ve gone to a Guatamalian lightly freshly roasted coffee; burr ground by hand just before I pour the water over the grounds and wait 45 sec to let it bloom; then pouring the rest of the water through it. I’m still finding it too bitter. I used 6 tablespoons for ~ 3, 8 oz cups. Should I try and adjust my grind, or the amount of coffee I add to the water to try and tamp down the strong bitter taste?
Drinking coffee without adding sugar can reduce the chances of heart disease and inflammation, thereby lowering the risk of cardiovascular disease  .

The National Cancer Institute has reported that men who drink coffee regularly are less likely to develop prostate cancer. A 60 percent reduction in the risk of developing lethal prostate cancer was found in men who drank 6 or more cups of coffee per day. Even 1 to 3 cups of coffee reduced the risk. Four or more cups of coffee per day have also been shown to reduce the incidence of colon cancer. Furthermore, researchers discovered that people who drink coffee are 50 percent less likely to develop liver cancer than their non-drinking counterparts. Additional studies have linked coffee consumption to lower rates of breast and rectal cancer.
A report from the International Journal of Obesity, published in 2010, noted that thermogenic compounds — like caffeine — might work better in some people than in others, or they might only work effectively under some circumstances. So while there's some potential for the caffeine in coffee to help you lose weight, you shouldn't count on coffee alone as a weight-loss strategy, at least until more research has been done.
