seizures
"I had my first ever seizure on 8/4/93; one day before my 24th birthday, out of the 'clear blue.' I was first prescribed 400mg of Dilantin daily. I experienced muscle spasms/twitches, sleeplessness at night [and] sleepiness during my waking hours. I was switched to 400mg of Phenytek daily. At first the same symptoms persisted, but subsided over time. I have been on both Dilantin and Phenytek for 22 years; currently on Phenytek and my seizures are controlled, with minor/minimal side effects; occasional muscle twitching and/or headaches remedied with Tylenol. I hold down a full-time job, and I drive, so my #1 priority every night is to take my meds. So far, so good....."
