Too many juices.

I have been juicing since Mother's Day and enjoy the making and drinking part. The cleaning up part I could do without. My quesion is, I seem to end up with loads of different things in each batch, eg, orange, lemon, apple, celery, carrot, pineapple, pear - all in the one mix. I seem to grab a bit of everything I have in the fridge. And some combinations have been so sweet, I end up with a Sugar headache. I am starting to think that it might be better to only have two or three different fruits or vegies in each juice at a time.
