Need advice regarding Depakene

Hi. I am new to this site, and have found so much good information on here. My son, who is 5, started having seizures while we were out of state. After his 5th seizure, our pediatrician put him on depaken. At first the dose was not high enough... Now, at one teaspoon (5cc) twice a day, he is no longer having seizures. However, he is extremely irritable, extremely tired, and eating everything in sight, as well as having diarrhea. My husband and the doctor both feel this is acceptab le since he is not longer having seizures (we are on day 6 of no seizures). I do not find this to be an acceptable quality of life for a beautiful five year old boy.In addition, I want his blood levels checked, and the pediatriican and my husband both feel it is unnecessary! I am so exasperated with my husband, and the pediatrician says to wait until we can get in to see a peds neurologist (which isn't until Aug.30). My husband happens to be a doctor in an unrelated field and for some reason that gives what he says precedence over how I feel and what I know as the mother. My husband is not doing any reading or research or learning more about seizures and our son's meds. It is driving me nuts. He also will not take off of work to go see the peds neuro dr. with us. In addition, while we were out of state, he would not and did not fly down to be with us (on a non working weekend) while my son was in the midst of his seizures (we ended up in the er at a children's hospital)...Any advice or help would be greatly appreciated...
