Tisanes

I love caffeine but if I have it anytime after morning it wrecks the quality of my sleep.

Herbal teas — less commonly called herb teas or tisanes (UK and US /tɪˈzæn/, US also /tɪˈzɑːn/) — and fruit teas are beverages made from the infusion or decoction of herbs, spices, fruits, or other plant material in hot water. They do not usually contain caffeine.
