Yah, like everyone else has said, you'll wake up feeling really weird and just completely out of it. I was actually really scared beforehand about the supposed pain afterward but it really isn't all that bad. Just take your meds and follow directions and you'll be fine.
Here's a funny pic my sister got of me when I came home. I tried walking into my house and quickly made a detour to the sidewalk/grass where I then decided to pull out my phone in an attempt to text my girlfriend. Needless to say, I was fucked up.
