I remember not liking the taste of the syrup when I started my first MC. Why not try to adjust the amounts a bit and see if that helps. I use 10 ounces water, 2 tbsp of lemon juice and 1 tbsp (not the recommended 2) of syrup. It's just to sweet otherwise.
But I agree with Pepe, you are definitely not getting enough liquids. You have to force it down- a minimum of 6 'ades and minimum of 6 cups of water!
