I have recently begun drinking yerba mate teas.  I was surprised that they really do help me in the mornings without the nervous effects that can come with the caffeine of coffee.  I have always loved chocolate and have been limited because of diabetes so this is a good way for me to sip and enjoy my chocolate.  I have to use this one very sparingly because of its expense but it is a treat for me.  I add a little half-n-half (or fat free half-n-half) and some Stevia and I enjoy every moment of drinking this tea.
