Tell him he can also have the shakes hot if he wants to.
Some people have the choc one hot with a spoon of coffee, or just as a hot choc.
And if you make a mug of peppermint tea then mix your choc pack into it then it makes a hot mint choc
My fave has got to be cold vanilla with a spoon of coffee though.
Your hubby should try that coz it's delicious!
Just stick to your 3 packs a day, you know it makes sense.
You can have tea, coffee with sweeteners, but NO milk hope this helps.
There are other drinks like coke zero, you will find mentioned in other threads
