i am not real up on medication. Since difficult child did so well with 150 mg's of Lamictal for about 18 months. Then things completely fell apart. Were changes in homefront too. Dr. raised Lamictal to 200 mg's. Along with other medication that didn't seem to work. difficult child actually got worse. Not sure if he would of continued to get worse of if the medications caused him to get worse. My question is if he did so well on 150 mg's, could 200 be too much? Would to much cause issues too?
