Okay, so I don't normally do painkillers, because whenever he does, (or any other potentially abusable pill), he recieves no affects. I am not a junkie and has no tolerance or obvious reason for this. I have taken 12 vicodin (I know its a lot... he worked up slowly after realizing they weren't working) and uses pills that are before their expiration date. I takes a large amount of zoloft, but has read no reports of such things happening. I also take (get ready..): straterra, an antihistamine, zantac, and singulair. Does anyone have any idea what could be causing SWIM's dilemna?
