Stress symptoms. From this problem?

Hi, As I have seizure I am regularly taking tablet as per doctor prescribed. Seizure is completely under control. Around 5 months back, there was symptoms started. It was like when working on office with laptop suddenly some blurred vision come, followed by some electric shock like feeling from head till almost for the entire body. This feeling and the blurred vision will be automatically comes to ok after 2 to 3 sec. When further consulted with a neuro doctor, he prescribed stress relief medicine (nexito plus) for month. After taking the medication for 2 week that shock feeling went away completely. After 3 months I stopped medicine. Problem started again after almost 3 week later from the medication stopped. This time even after taking the Same medicine for more than 3 months, problem is not going away completely. At least once in a day that blurred vision and shock feeling comes back. What should I do to completely get cured from this problem? Please help Regards Jegan H
