Candace, my daughter was having problems with her 8 yr old daughter, not wetting during the day, but not being able to stay dry at night. She was also having periodic stomach aches (cramping that would wake her up during the night and make her double over) that didn't manifest into anything else. At my suggestion as a 'test' she took her off all milk products (no milk, no ice cream, a little cheese only; uses rice milk for cereal and protein shakes) and within 2 days the tummy aches stopped and she has stayed dry for about 2 weeks - plus the dark circles under her eyes are gone! It could be something as simple as that for your son. You may want to try an elimination diet, one thing at a time (i.e. dairy products first, wheat/gluten products next if dairy isn't the problem). As you know, it's always best to try to find the actual problem and then a solution rather than medicating away the symptoms like your doctor suggested. Best wishes on sleuthing out the problem!
