I was checking out this site dealing with percs, vikes, oc etc. They have a list of otc drugs that enhance the opiates. Its at http://www.coldwaterworld.com/potentiators.htm
I have two on the list, doxylamine succinate and naproxen sodium (aleve). Does anyone know if they are safe to combine? The page tells what each one does with opiates, but doesnt talk about interaction. Thanks.
