I took it for severe epilepsy. I had two children on it fine, no problems. It put my epilepsy into complete remission, but for all the years I took it my life was destroyed by the emotional and mental side effects. Ended up homeless and in a domestic violence relationship, which I got out of when I stopped taking the poison pills. Coming off it felt like waking from a bad dream, but without epilepsy.
The effects which never went away were the dry mouth and no sweating, the enamal is stripped off my teeth. The mood swings and depression and exhaustion and memory loss and cognitive damage never went away. The loss of appetite and extreme weight loss(92lbs at 5'1" at first, 98lbs after tolerance) never stopped, nor did the constipation and resulting hemorrhoids.
Initial dose increases caused what I understand to be myoclonic spasms, which was a change in my seizure pattern, and other seizure pattern changes. The spasms came immediately after the final dose increase, were incapacitating in severity and lasted for about a half hour, and didn't fade for a week or two.
Did put epilepsy into complete remission.
