I like my cbtl coffee maker and I drink a variety of coffees colombian, kona, vienna, costa rican and i like it with cream no sugar.
The reason I can drink coffee and remain unaffected is because I'm a fast processor of caffeine. I always wondered why I could drink coffee and go to sleep. We had our dna done by 23 and me it's extremely interesting and the price is down to $99. for the complete package. That's how I found out I was a fast processor of caffeine and if you are a slow processor you will get jittery and it could be dangerous but actually kind of good for you if you are fast.
I usually only drink it in the morning sitting in my recliner watching the weather channel it's a very relaxing experience.
