I have been taking morphine sulfate 15 mg tablets to get high but I haven’t been feeling shit. The morphine is expired by like 6 months but it hasn’t been deteriorating or anything. All I feel is slight relaxation with nausea and headaches. And for some reason I can’t piss either?? Like I struggle to piss off of the morphine. I have been taking 60 mg doses, so 4 tablets. I normally just swallow them with water. Does anyone know why it’s not getting me high?? I know the tablets aren’t fake either because they were prescribed by a pharmacy. I’m also thinking about just taking a higher dose.
