In addition to the advice below, it sounds like you may be eating too little- A baseline estimate for calories burned is 100/mile, so if you ran 18 miles you likely burned at least 1800 (but it's probably higher given your speed, heart rate, etc)! I am nowhere near your weekly mileage (I do 20-25/week) but I do adjust my intake accordingly- you are also almost at your goal so losing will be more difficult.
But to me, it sounds like you're not eating enough. I would put into the fitness calculator that you burn at least 4000 calories/week and see how it adjusts your food range. I think you're right to eat more on days you run more and less on days you don't run/run less.
Hope that was somewhat helpful! And I can't recommend a heart rate monitor enough if you don't wear one!
