yeah i went through that stage aswell, got on the uppers for to long and lost the high and ended up being edgy when i was on them and didn't even enjoy it yet would keep smoking more thinking it would pass but of course made it worse 
i took a break from them for a good period and enjoy the high again, i guess thats the only thing to do. hmm K also brings down your amphetamine tolerance
