I love Ganoderma coffee! It does not raise my blood pressure, make me crabby, dizzy, or shaky like other coffee does, yet still manages to wake me up and make me feel great for the day! I find I only need one cup in the morning instead of the 4-6 cups I needed of regular coffee, too. I have Lyme Disease-induced ALS and this is the only coffee that I find healing and soothing to me. I didn't have to give up my coffee in the morning! The ONLY improvement they could make is to offer a Hazelnut version of the 4-in-1. That would be delightful!
