Hey there, PurpleHazeMaster.
Sorry to hear what you're going through, but look at it this way. All this testing and medicine and the driving restrictions are to make it so you're safe to proceed with the rest of your life, which you'll likely be able to do very shortly. With as much wide-open future as you have in front of you right now, the last thing you'd want to do is get out in a car, drive someplace, and have a seizure and kill yourself or someone else. Seriously. Giving up driving temporarily while they get your diagnosis and meds straightened out is a fairly small sacrifice compared to that, right?

Phenytoin is a very common seizure drug, and it's wise to heed that advice about not drinking while you're on it. Actually, any drinking you might do isn't good for the seizures themselves (it can trigger them), and then there's the drug interaction with phenytoin on top of that. I think it'd be wise not to smoke weed right now, either, just for good measure. It probably wouldn't hurt you, but no one knows, and if you're going to be facing surgery, your lungs and entire body need to be as clear as possible, both from weed smoke and tobacco smoke, so you can tolerate anesthesia well and heal once any surgery's over. Some doctors believe cigarettes can be seizure triggers, too. It doesn't matter how much you think you need cigarettes, your body needs you not to smoke more right now. Exercise will help you deal with the stress you're under if you need a stress-reliever.

I don't have a seizure disorder, but I have had brain surgery to correct a malformation that I apparently was born with. I had to go through all that same stuff you're going through, only fortunately seizures weren't what started it. Visual trouble and balance problems were. I know several people who do have seizure disorders, however, and they manage quite well. Surgery is scary, but it's not as scary as living with the consequences of not doing an operation when it's necessary.

Yep, brain stuff is scary. It's heavy-duty, too, because that's where you live. That's why you have to do everything the docs and medical folks tell you. Because it's serious and practically everything you do starts with--and in turn affects--the brain. Let me know how you're doing!
