Try this instead of a milkshake. a cup filled with ice
heavy whipping cream and a sugar free syrup. (DaVinci is mentioned a lot in this forum. There are other brands) Vanilla is great but so is orange and cherry. For a 16 oz glass we use about 3oz syrup and fill the cup with cream. Blend in your blender. It comes out smooth and creamy. A real treat. and you stay LCing
Hope you feel better
