I was a bit worried first time I was gonna drive high, but I did it fine and realize it was no big deal.

I'm not recommending you do, but if you do, be careful. I've driven high a few times and was fine, just remember to pay attention.

If given the opportunity to not drive, I suggest you take it. You'll probably be fine, but if you don't have to drive thats one less thing to worry about.
