I had the same side effects as you I hated it and almost quit it on my own. Everything made me angry, I lost interest in everything and became apathetic to everything. I'm on 1500 mg 2 times daily. It took about six months for the anger and temper to subside but I still have no energy or drive. It as if nothing motivates me. I have tle left side I was diagnosed in 1995 but have had it my whole life looking back. When I would have a tonic clonic seizure I usually would lose memory but since keppra I don't have as bad postical problems. Although 4 years ago I had multiple seizures that left me in a Coma for 5 days and lost 13 years of memory including my children growing up. Thats when I started Keppra. I still don't have much of a short term memory and have trouble finding words. Enough about me if you can tough it out it might have benefits as it has for me but the first 6 months was hell.
