I drink earl grey, green, black, and cinnamon herbal tea, and usually sweeten with a little bit of honey, otherwise with nothing else in it. Sometimes I'll add lemon to black or green tea. All hot.
I typically drink Assam, Yunan and Earl Grey. I used to add honey or sugar but lately I drink it without adding anything. I like to add milk every now and then. If I knew how to make chai late at home I would probably do it more often. When I drink green tea I add nothing - tried different things, but they never worked for me.
Sugar or honey (usually the former because I always forget that I have the latter in the cupboard). I've had tea with cream before, and it was quite good, but I don't know what the specific varieties were.
It's a pain trying to hunt down specific teas without knowing what they are. I remember having a delicious Jasmine tea years and years ago, but it was a dark tea, and the only Jasmine teas I can find in the stores are all green tea. So it's just not quite the same.
