In 2013 I was diagnosed with an Irregular Heart Beat and minor leakage in my heart valve. I discovered these conditions after sipping on my regular cup of coffee one morning and getting mild chest pain and having difficulty breathing. I went to the Dr. to check out the issue and had some heart tests that showed I have an Irregular Heart Beat. I then had further heart tests that showed I was normal in other areas of my heart though. My Dr. told me that I needed to stop caffeine such as coffee, soda, and chocolate etc., which would help and could help me from developing Afib and other heart problems. So I stopped all caffeine. I discovered Teeccino in a health food store and I have been regularly drinking it ever since hot and cold and LOVE IT very much. What a geat coffee substitute!! I don't even need sweetener either! It's delicious as is! I just had my yearly heart tests and I haven't changed or worsened since 2013 and I credited to NOT using caffeinated drinks or foods. I don't even have to take medications for these conditions as well. I'm so thankful and Teeccinio has been a big part of my good health results too. Thanks Teeccino for all your great varieties of amazing flavors, and the ease of ordering them online too. I enjoy them very much and hope others try them too, esp. if someone has heart conditions it's a great alternative!!!!
