Clonazepam
"I have taken Klonopin for at least 20 years now and it is the only medication that prevents absences and myocloptic seizures. Sometimes I have breakthroughs but not often. I vary in my doses from 1 mg a day to 3 mg at times due to needing a little more or less. Since I have been on it for so long I am able to do this. I take it at nighttime because I cannot function during the day if I take it in the morning.  I think I have been on every seizure medicine there is and have had nightmare stories concerning them but Klonopin works the best for me. I believe every person is different and what works for one may not work for another. I do have to put up with occasional side effects like bouts of insomnia and breakthrough optical migraines."
