I can't have caffeine.... But when I would drink coffee I had full fat cream or half and half. No sugar. I liked green tea and oolong better than black tea and would not put and sugar or cream in. I also really liked mochas but they just have too much sugar.
Now I just stick to organic herbal teas. Mainly peppermint or Chamomile with Lavender. No sweetener of course. Speaking of, I think I'll brew up a pot of cham lav.
