As someone else mentioned, a good replacement for morning coffee is tea with a little milk and sugar, but I want to add that, like coffee, certain teas have more or less caffeine in them than others. Since it sounds to me like you're wanting something that can replace your coffee, caffeine wise, you'll want to make sure to buy teas that are "Highly Caffeinated". This means you want your teas to have at least 100 mg of caffeine, since on average, a typical cup of coffee has 108 mg of caffeine and has about 15 mg of caffeine per oz for an 8 oz cup.
My personal recommendation if you're switching from coffee to tea, is Fast Lane by Celestial Seasonings, however it is out of stock and is only brought back for a limited time, so you're probably not going to find it in the stores. My second recommendation is Pacific Chai Teas. You can find these in a variety of flavors at your local Walmart. It is technically listed and sold in the "Coffee" section and is categorized as coffee but it hasn't any coffee in it. These are the ingredients:
Sugar, Nondairy Creamer (Coconut Oil, Corny Syrup Solids, Sodium Caseinate (A Milk Derivative), Dipotassium Phosphate, Sugar, Mono and Diglycerides, Silicon Dioxide, Tetrasodium Pyrophosphate, Soy Lecithin), Nonfat Dry Milk, Sweet Whey, Black Tea, Natural and Artificial Flavors, Spice Blend (Cinnamon, Anise, Cloves, Ginger), Honey.
The great thing about this drink is that it is ready to go and is in a powder form that you just add hot water. No milk or sugar needed (though you can still add if you desire). In a 12 oz glass you get 100 mg of caffeine and 8 mg/oz.
If this isn't really your "cup of tea" (haha) you can get earl grey / regular black teas (which I've been told are the highest in caffeine) and just make your own mixed drink. Best of luck!
