Why are my leaves curling? Cherry tomatoes are really healthy. Watered them like crazy... No difference

It's hard to say without seeing the plants. Are there any insects? Aphids can sometimes cause leaves to curl, but are easily brushed off with a blast of water. Is there any possibility of contamination from herbicide applications nearby? Sometimes folks apply lawn weedkillers in windy conditions, causing the herbicide to drift over areas they don't intend. There are also possible virus infections, but that would be more difficult to diagnose. Here is a document from Texas that explains several causes of leaf curl in tomatoes: http://aggie-horticulture.tamu.edu/vegetable/files/2010/10/E-626-What-Makes-Tomato-Leaves-Twist-or-C...
