I have 3 vicodin (5 mg hydrocodone) and tons of 25 mg promethazine pills. I will only get a buzz from the three vicodin so im planning to pop some promethazine pills with the vicodin, but i don't know if it will potentiate it or not. If the promethazine will do anything, how much should i take? and will it be like a promethazine/codeine syrup high?
