You're happy feelings quickly turn into extremely negative feelings. You know when you have the flu and you just have that almost indescribable malaise; like a pain or aching of your entire body? It is just an incredibly uncomfortable feeling both mentally and physically. If you don't have a sedative to take, you will most likely spend a few hours lying in bed feeling like total shit, tired but cannot sleep.
During this phase, you will be most likely cycling through extremely depressing thoughts and anxiety in between moments of extreme hunger for more Cocaine. Essentially, what goes up must come down with Cocaine. What you get up front, you inevitable pay for on the back end. This doesn't even include waking up the next morning. If you were drinking Alcohol as well, this will be a difficult experience.
