Not from what I have seen, a friend of mine was sitting around in his living room on a self-admistered I.V while he was on leave talking about how great all the stuff he learned is.
Friend: You haven't slept in 3 days? Put this I.V on for a while and you're good to go, wanna try?
Me: Nah, I'll take your word for it.
Maybe Rangers are just crazy like that though...
