Tegretol and dilantin are the 2 epilepsy drugs they almost always start you off with. I'm on 300 mg of tegretol for several years now. When I was first diagnosed though, I was on 900: 600 in the morning, and 300 at night. It pretty much destroyed my life. At the point I became aware of it, and the 3 week adjustment period had ended, I contacted my doctor and we began playing with dosages. Ultimately, I got to 300 in the morning and 300 at night. I found the slow release stuff worked better and insist on getting the brand name stuff rather than generic.
By destroying my life, I mean that I got vertigo so bad I could hardly stand up. I was tired all the time, even after lots of sleep. I spaced out a lot and had trouble concentrating.
The lower dose helped but i, like your boyfriend, had many auras each day... And I just lived with it. I kept a diary once and noted an average of 8 per day. My auras were involuntary jaw, tongue, and mouth spasms that made it sound like I was stuttering when I talked. The auras would last for minutes. Sometimes, my lungs would spasm as well. I decided I would rather cope with that than vertigo, spaciness, and fatigue.
One day, after some things had happened, my neurologist decided to try a new drug in addition to the tegretol. So, we added keppra. I hardly ever have those auras now. I have different auras.

but, at the same time, my life is much much better. I still have the odd seizure, but it's a quality of life that works for me. Since adding keppra, I have reduced tegretol to only 300 mg per day in the morning. I hope to stop taking tegretol entirely if I can have about 6 months with no seizures at all.
Some suggestions... If your boyfriend has been on tegretol longer than a several months,
- try experimenting with different and lower doses. My blood level is on the low end. They look for 4 - 10 for treatment, and i'm usually 5.1. At a lower dose, he might have exactly the same level of auras... And if that's the case, why bother increasing the dose if it causes such bad effects?
- once comfortable that things are not out of control, talk about adding a new drug with your doctor. Don't be shy to contact him either.
- your doctor's goal is to make all the auras go away and all the seizures go away. But, our medical practices advocate drugs... Which often cause side effects... Which are then treated with other drugs. I suggest a minimalist approach and finding something that works for him. Be patient with him. Epilepsy is not fun and you should be patient with yourself. To be honest, he should be pursuing his own treatment, not you.
Lastly, some people have problems with partial seizures in their sleep. Because they are sleeping, they aren't aware and don't remember, but it affects the overall quality and quantity of sleep. My wife notes that many times in my sleep, i'll stop breathing and then startle myself awake. Over time, this alone will tend to make you tired and lead to massive 2 or 3 day crashes.
