Use a hand held blender/chopper to mix your shakes. They won't be chunky anymore. Use dextrose in every protein shake. It will help with the taste. It will also help speed up deliver of the protein to your muscles. You need carbs with your shake, everytime you take a shake. If you are using a chocolate mix use Milk, it will always taste better than water. If you are using a fruit flavored mix use water and mix some powdered gaterade of the same flavor and use it as your carb source.
