Covert Op

I am perscribed adderall so I am not worried about failing for amphetamine. Do stimulants like adderall help clean out your system any faster? I know it increases metabolism, makes it easier for me to eat healthy foods, I think its a diuretic because water seems to go right through me, It speeds up my gastro intenstinal tract so i shit my brains out...and i take fiber alot so im hoping this will really send the detectable metabolites through my feces...any thoughts...sorry im being so graphic but i have a really good job offer and i've finally been able to quit smoking which i've never been able to do before and itd be a shame if i failed after taking unnecessary time off.
