welcome to addiction
I really like cappuccinos/macchiatos, and iced lattes. I prefer to add 1/2 tbsp vanilla syrup for the iced drinks. I have my own espresso machine and it is 1000000% worth it, I recommend the Saeco Poemia, it self tamps and has a steaming/frothing wand. It's also very easy to use and maintain.
My gf makes a fantastic chocolate chai. Also tea and cream made by my Pakistani roomate - it's basically cream with some tea sprinkled on top. Fantastic.
I like flavored coffee and tea. I really like pumpkin spice or cinnamon flavored coffee and chai tea.
As for cooled drinks I only drink iced tea or plain water. Sodas and energy drinks are something I always avoid.
