epilepsy
"I cannot stop singing its praises. Two years ago I had no idea what was wrong with me, I felt "fogginess" and tried everything- declared "headaches" caused by anxiety or depression, had to take a year off of school since I couldn't function; xanax helped but I didn't understand why, and about 17 other antidepressants or antianxiety medications later I was put on lamictal due to a diagnosis of BPD. Almost instantly, from that initial does of 25mg I started being able to focus and the fogginess lifted. As the dosage increased to 150mg to twice a day, I was given back all waking hours of clarity. I could focus, produce, study, think clearly, remember clearly, everything. As a result of being given power back, the depression vanished."
