It's hard to say, man. Everyone is different. Personally, when i was young and had no benzo tolerance, 3mg had the potential to make me black out for half a day. I would be alright by the next day, but definitely not 100%. Just make sure to get as much sleep as you can. Wake up, take a shower, eat a solid healthy meal, drink a coffee. You'll make it, but I can't say you'll be sharp as a tack. You took a pretty high dose for someone with no tolerance.
