I have been an avid coffee drinker for 12 years, can't start my day without it. I was told to cut out caffeine by my doctor to stop my rls (restless leg syndrome); I get it really bad in my arms, and to stop the jittery nerves and mood swings. 2 days without coffee I was desperate and googled coffee substitutes, Teechino was the first link I clicked on, I ordered 2 boxes of bags and I am hooked for life.... I will never go back, my energy is all natural without that sugar high I used to rely on, I'm sleeping better at night and my rls has greatly improved. Thank you so much for your products, I can't live without them!
