My son is 8 years old and has been taking lamictal for 3 days. He complained of being really tired yesterday and fell asleep around 2:30 in the afternoon and slept for 15 hours straight. He woke up fine this morning. I am concerned about him taking this drug and not sure if the risks outweigh the rewards... Does anyone have an idea about how long this fatigue will last or how beneficial this drug is for a child with bipolar disorder?
