I like a nice ginger tea after lunch... aids the digestive process and tastes delicious. If I have it at night though it disrupts my sleep.
So in the evening I usually have a peppermint tea with dinner followed by a camomile tea.
They taste great, make you feel great, and give me a very peaceful, deep sleep.
I may take a walk on the wildside though. Perhaps through excessive experimentation.
What herbal teas do you go for?
