When fasting I find that I get very cold despite putting a few extra layers on under my work shirt. Unfortunately I can't take even decaf tea of coffee because even the minimal caffeine content makes my acne really flair up (and I never take milk which also makes me flair up).

Can anyone suggest a suitably primal hot drink that is naturally caffeine free? What about some of the fruit teas? I'm unsure about their 'natural flavourings'?

Thanks!
