I have been taking selzic ( 450+600 mg daily) for the last 4 years. I have had seizure twice during this period (last one occurred 2 years black). Of late this drug has started to show some side effects. On some days i sleep for long hours and yet feel tired throughout the day. On other days I dont have a good sleep but still feel fresh in the morning . Kindly tell me if i need to decrease the dosage and stop it completely at the earliest
