Hi Julie - In regards to your message about your son, I also have a son that I feels gets "pooped out" earlier than others in age in all activites. I just talked with Carol in regards to this and she questioned whether he has always been like this. Actually, he has. He never has had any get up and go! Just wondered if your son has always been like that also or has it happened as he has gotten older.My son is 9 yrs., 3 mos. and, as is doctors say, is extremely well controlled. However, I am concerned as he is getting older that he doesn't participate in many sports because he does tire easily. Also, is your son on cortef or dex and has he experienced any weight gain problems?
