Well, you posted on the low calorie forum, so skimmed milk is the only way to go.
190 calories per pint.
Next to no difference in the carbs.
It's all I drink, in coffee, and for the amount of milk per cup, the amount of carbs fall well within my tolerance.
I hate cream in coffee, I'd rather have it black than destroy the flavour with such an overpowering high calorie taste.
I would suggest, if you have a meter, check after a cup of tea with skimmed milk, you won't destroy the flavour, and you may be pleasantly surprised.
