Had this again last night. I had an appointment with the accountant previously, and a 7:30 am dentist appointment this morning! I probably could have used something much stronger than rooibos, but, since I have an active imagination, it sufficed! I felt warm, comforted, relaxed, and fell asleep (and stayed asleep!) within a half hour of my last, tasty, sip. I really have to look into some more flavors :)
