the coconut creamers for coffee (like so delicious/silk brands) are just a carton of sugar and chemicals. IMO, have the full fat dairy (1 or 2T heavy cream isn't going to hinder your progress, imo. Several glasses of milk, cheese, yogurt, etc every day will. See the difference?)
you can score some coconut cream concentrate from Tropical Traditions & mix that into your brew. It's straight fat & oil, and is great in hot drinks!
