To coffee lovers..plz help

Id like to start drinking coffee to help me stay awake because I'm going to start rotating between night and day shifts at work but I absolutely hate the taste of coffee. Can anyone on here recommend a drink from Starbucks or Panera that tastes the LEAST like coffee? I like caramel flavor or chocolate anything and I have a feeling id prefer iced over hot..I just want something that really masks the coffee taste to make it easier to drink.
