so, ive tried codeine 4 times, and didnt feel anything. My max dose was 100-130ish mg. What would be the recomended but safe dosage? Ive seen divergent info on differente websites. I have liquid codeine syrup 3mg/ML, and dont know if i took too low of a dosage or if I simply dont metabolize it. So, what dose should I try to actually feel it? If I didnt feel 100+mg, do I not metabolize it into morphine?
