Shower floor symptoms and conditions

I've been on Lamictal for 3 years, and it's started to fail. I was on a generally small dose for epilepsy, 100mg twice a day. Well, I started having these twitches that caused a car incident, so I had to go to the doctor to get the dosage increased. Well, I did that, slowly, and I was twitch free. I thought that this was great, I can finally rest easy. Also, for some reason after I increased the dose I was oversleeping. No severe side effects though. But then, just yesterday, I had what we believe to be a full fledged seizure during a shower. I missed my dose by 2 hours the night before, and luckily I was having trouble falling asleep (or perhaps unlucky), and I probably got 5-6 hours that night, which lack of sleep is always a bad thing with epilepsy. So, during my shower I started twitching, bad. I turn the shower off. Then the next thing I'm on the shower floor, and I see blood on the wall, though too dazed to make anything of it. My family hears the bang and comes down and tells me to open the door, but I yell out to wait until I'm dressed. Then I felt horrible. So obviously the dose increase didn't help, and the Emergency room doctor put me on Depakote plus the lamictal until I see a neurologist next week.
