I think that fent is one of the better(if not the best) painkillers.And even if i read here that it doesn't give you a warm,euphoria opiate feeling,i don't agree with this.For me it works still with my pain,even that i take it for 7 years at the dose that i started it,i didn't increase my dose.And if i take 2 pills of ketoconazole or 2 clarithromycin,it will give me a nice,warm,opiate feeling for all the day.Please don't do it if your tolerance is low or medium,it's a very bad idea.Some others think that it's a strong but "cold" opiate,i understand this.the same drug works different for everybody,and of course all the people doesn't have the same taste..But as a matter of fact,i would like to get some(lot)oxymorphone,probably it's the best opiate...
