I am a chronic tea drinker. I would no longer call it an obsession, it's more of a debilitating habit--without the debilitating part. I can actually survive without it. I just prefer not to.
My favorite teas are unflavored black teas. Occasionally I drink some herbal tisanes, but not as a habit. White teas are okay, and green teas are something I have yet to acquire a taste for after 10+ years of habitual tea drinking.
But my cupboards are filled with more than just my morning, afternoon, and evening unflavored black teas. Yes, I have different kinds for different times of the day. That's very important. I have some flavored teas as well. Now, I know you're thinking that these are reserved for guests, and you are partially right. I do serve my guests the flavored teas if that is what they desire, but they're also for me.
I drink flavored teas when I am in weird moods. Cinnamon is for when I'm sick. Chocolate mint is for when I'm feeling romantic...don't ask. Earl Grey is for when I'm feeling a bit down and weird at the same time.
Then there's Darjeeling. I know, it's not technically a flavored tea. It's just so different. I can't say that I actually like it, but there are times when I want it for some inexplicable reason. When I get the reason figured out, I'll tell you. I suspect it has something to do with being simultaneously tired and hyperactive.
Just keep the green teas away from me. I have yet to be in a weird enough mood to actually want one of those.
