I'm glad to hear you haven't had any siezures. My boyfriend has had 2 grand mal siezures from benzo withdrawal, each siezures was almost 5 minutes each. They are no joke. I would recommend that you don't drive, take it easy today. Call out of work. Just rest and try to relax and sleep if you can. If you can't find any benzos today and you feel like you can't take it anymore, go to the ER and they will help you. They have sick addicts in there all the time and they won't judge you. And because you're worried about siezures, maybe you have a girlfriend or friend who can come over and keep an eye on you today so you aren't alone if you do end up having a seizure.
