Hello, I have had 2 seizures in the past 8 years. I was taking Xanax 2mg. 2 times daily. I ran out early both times, and was taken to the emergency room both times. I did some research on Xanax, and discovered it has a very short half-life, so it doesn t stay in my system very long. It works fast and leaves my system fast. I have switched to Clonazepam, which has a half life of up to 60-80 hours, whereas Xanax is about 4-8 hours. I have run out of my Klonopin several times due to self-medicating on several occasions. When this happens I have several BAD side effects, which include irregular gait, speech, teeth grinding, problems with balance, and holding on to walls as to not fall down. However these symptoms are controlled nicely if I take my Klonopin as directed, and do not run out. Are these symptoms of stroke OR another seizure? Regards, Joseph DeCapua/ Royal Oak, MI.
