So I read on Erowid that a good starting dosage for codeine is 30-60mg, but I've read many other places that this is quite a low dosage. I was considering taking 90-120mg, because this is a one-time chance and I know that dosage will be fine. I want to take enough to be sure I will feel the effects. I could really take as much as I want, but just once. I have never had a true opiate high, but I have taken Vicodin (multiple times, at pretty high dosages) before and it does not work on me. I took it multiple times, only confirming the fact that it doesnt work. I am also a big guy, 6'4" and 190lbs. What do you guys think a good dosage would be? Is 120mg even enough?
