  I don't know, the metabolic half-life for dopamergenic stims is typically 2-3hr, so you could technically get a 5 hour coke buzz if you did a whole gram in a night, ending at 12, you'd still feel a bit frazzled by 5 if you stayed up.   I've done it before, with 90% pure shit, hard-rock from the brick.  It wasn't fishscale, I've found fish is potent other ways, but I would be careful putting it in my nose, unless its real puro.  All coke should be crushed and chopped into like small grains of sand, slightly coarse, and snorted into "The gulch" which is what I call the place inside your nose but not down your throat.  We did like 3.5g in one night, I finished the night with a 125mg IV shot, it was pretty fucking hairy, I thought I was gonna die.  I never did much coke after that.  The thing is, you can be frazzled(over-stim'd), but you shouldn't be like "fuck I can't sleep" like 6 hours later, if its that, you got methy/ethyl-phenidate or some shit, but even that kicks off. 
  Only D/L-amp and cathinones last that long, typically.  Sounds more like cath salts to me, if you didn't realize what it was.
