Anyone have a calorie estimate for flavored coffee from the gas station? Because I got to go to work late this morning because of the ice

I splurged and filled up a large coffee cup from Valero about 1 cup full of Dulce de Leche coffee and then filled the rest with regular black coffee. I estimated 120 cals - think I'm in the ballpark?
Also, maybe I'm just posting so I can brag

!! I fit into my size 12 pants yesterday!!!! Whohoo!!! And the best part is, I thought they were my comfy size 14's, and I wore them all day without even realizing they were the other ones - so they weren't just fitting, they were comfy!!
Ok, done bragging. (Sorry, I have no one else to do pant shout outs to!) Any idea about the coffee?
