Hi Nikki,
Yes, coffee has carbs. I believe its 1 carb / 8 oz of regular coffee (really .967 gms per 8 oz but rounded off it = 1 carb). What I would do is take a HUGE mug to work, probably 24 oz, add one table spoon of heavy cream which has 0 carbs according to the carton but it could count as one. Then to sweeten it up, I would use Davinci's Sugar Free syrup which has 0 carbs, vanilla or what ever flavor I could find, either via internet or Walmart. So you see, my BIG!! 24 oz coffee would only be 4 carbs at the very most.
Hope this helps.
Splenda should be counted as 1 carb per pk as well.
When I got to work I would use liquid sweet n low (I know I know) but it has 0 carbs
