I don't drink much milk unless I can get it raw and for us that is usually goat's milk we get from a friend... my wife finds it much easier to digest than cow's milk although she has gotten better with this over the past three to four years as she has dealt with celiac disease which impaired her ability to digest dairy products.

I do use a lot of heavier cream (18% and 35%) in coffee and cooking... it adds a good amount of calories with no carbs which suits our diet and also use a lot of coconut oil as it is highly nutritious, calorie dense, and easily digestible... it is closer to mother's milk in this respect and requires less enzymes and proteins to process.

1 cup of 3.25% milk has 103 calories and 8 grams of sugar while 2 tbsp of heavy cream has the same caloric energy via fats and no sugar... coconut oil is double that per tbsp and is one of the most easily digestible foods we could eat and has a fast energy return.

Chocolate milk is favoured by a lot of folks as it has three times as much sugar as regular milk and about as much sugar as a similar amount of soda.
