What are the immediate symptoms of levamisole?

[moeburn]

So I've got some coke, but I've never really done that much coke before, and I've only ever done stuff tained with levamisole before (as confirmed with urinalysis). What's the difference in effects/high between pure coke and levamisole-tainted stuff? Other than the scientific stuff like lowered white blood cell count and necrosis. I ask because I find after a few hours of coke binging, I feel like I'm sick, like I have the flu or a fever. I suddenly get extremely tired, like I can't move, and I just fall asleep, even more coke isn't enough to wake me up. It's the same kind of general malaise that I get from a mild cold or flu. I was just wondering if this is typical of coke hangovers, or if its the levamisole doing it?
