IIRC that is what caused Rush's deafness. Remember when he was hooked on oxy?
That would be the last thing I'd take.
You are mixing up two things. Rush was hooked on OxyContin, a drug made from opium. Prescribed for pain but sometimes used as heroin. Oxytocin is a hormone released while breastfeeding and after orgasm, a warm, feel good sensation that is probably meant to increase closeness. I have no idea about Limbaugh’s orgasm history but I’m pretty sure it was OxyContin he was abusing.
