Coffee just gives me bathroom breaks and makes me feel like I'm imploding. I'll drink it if it's a mixing ingredient for alcohols. Shot of rum, dash of bailey's chocolate shavings so you pretend you don't have have coffee cup with at least 12% in it.
Boiled weeds and fruit (tea) have more diversity but I haven't found a non alcoholic recipe for iced tea that I enjoy.
For the buzz one, Fruit tea, (forest fruits, berries in that direction), Jagermeister, sweeten with grenadine instead of sugar. Add pine seeds or muddled berries if you want to be instagram fancy.
