Wait two days. I dunno about others, but I only really want more for the day after.
If you mean during the comedown, a bump or two of K and voila! A couple hours later you're out, and you didn't even notice the comedown.
It's all in the mind, ya know "bend the spoon, yada yada yada.."
Things that helped me:
1. No more money, no more Coke, the shit's expensive.
2. A good look in the mirror after I'd been up for a couple of days, yuck!
It's really just a matter of proving to yourself which is stronger, a little bit of white powder, or you
sometimes when im coming down ill pop a sleeping pill so i get knocked out before i start to really feel like shit. but then im all grouchy the next day, heh. but like to surpress the urge to do more, yeah i agree you just gotta be strong and not give in to temptation.
