I love coffee, but I now limit it to the morning/pre-cardio, because it was affecting my sleep and promoting anxiety. If you're dealing with bitter coffee, maybe you need to change up the brewing method. I used to need non-dairy creamer, but the more I learned about coffee, the less I needed it. Have you tried a french press? The other option would be to use Almond, Coconut, etc. Milk and a Torani flavored syrup. Maybe you could mix some coffee with vega mocha protein powder?
