Play around and see what works. I used to like sugar and milk with my tea, and I still do with certain teas (English/Irish Breakfast, for instance). If you're used to strong coffee, you should definitely check out English and Irish Breakfast teas. They are strong black teas, very robust flavor.
Right now I am drinking some Echinacea Immune Support from Yogi Tea:
Welcome To Yogi I love their herbal teas. Yes, they're all bagged teas, but I really think tasting the bag depends on the quality of bag used. Loose teas are good but they're not always practical. I keep a "cold care kit" in my backpack made up of Yogi Teas. My cupboard is just about overflowing with Yogi Tea.
For loose teas, I have a couple different infusers that I use, one from Bodum and the other from the Republic of Tea. I like both. I buy loose tea from a variety of shops around town. If you are interested in loose tea, look for a shop with knowledgeable personnel; it's really nice to be able to go in, talk to the shopkeeper, and walk out with the perfect tea and some good advice on how to brew it. I have a really lovely stoneware teapot that I love using, especially during cold season, because then I can just brew a giant pot of whatever it is I feel like drinking.
One thing to remember is temperature:
Tea Brewing Temperature Guide and steeping time. Different kinds of tea require different water temperatures and steeping times.
