^^ 60mg codeine is 6mg morphine, in the ER, not knowing your tolerance, if you're hurt they will IM 30mg's of morphine..
fine, you can do 60mg and not feel shit, and it will be a big dissapoinment, or you can take 200mg, and get a slight idea of what codeine/opiate high is like... all the people i know started with 1 box of OTC codeine... 300mg... including me, the only thing i should have done is take an anti-histamine before hand
if you do a 10mg test to check you're not allergic, 300mg or 200mg is in no way dangerous for a first timer.. no where neaaaar OD levels
