i had sorta the same thing once..spent 3 hours trying bust a nut but couldn't apparently it was do to some meds i was taking to try and quit smoking i had a left over prescription which was short of expired so i used it for a second quit, well it had gotten hot inside the apartment apparently above the temp limit for med storage... anways i also got serious dizzy spells and felt sick to my stomache... side effect of the med is decreased sexual functioning i might even have gotten mildly poisoned if the meds had indeed gone bad lol sucked ass
