Sparky - how much is enough??

so... within the past eight hours... I've done realized and thought about everything I did today and I'm wondering why my state of mind isn't all gone... or is it???
so yeah... how much narcotics, prescriptions, alcohol, dietary supplements and tobacco can one person be on before you see any signs of abuse? IDK... apparently... in my situation... it's all high tolerance or I'm just going insane. seriously. I'm so fuckin' miserable that I've done had about seven different types of substances today and wonder why the physiology of my body has not changed yet?? or has it and I just haven't caught onto it??? who knows... I just need my fuckin' shit... before I go insane... seriously.... truth be told that I am know be a lil' psychotic, corrupted, and emotionally disturbed. so yeah. IDK and I probably wont know, so we'll just leave it at that.
