after all this time i've always found myself more irritable after a dose of oxy but never gave it any thought. i suppose this might be due to the stimulating properties of oxy making us edgy at timesYou’ll need a lot more codeine to get to the same place. Also oxy tends to make me and others sort of “irritable” and I never noticed that with codeine, although it was always just shots of cough syrup, and usually not getting super faded.
