No, you will not. You'll be awake, but your eyes may have attempted to implode on themselves. Either way, people can tell
From personal experience, find a nice SAFE (seriously, avoid hot or sharp projects, I know they're tempting) art project, some good background music (to drown out the paranoia), and up to three days of free time(time really flies and a day becomes three faster than you can order a cheese burger for the crash)
Also, cheese burger, you won't have eaten since you took the stuff, any food really. (Kinda like coke only worse or better depending on your views of your bodies natural function).
If you smoke you need a carton of cigarettes.
