I got hold of some 60mg codeine tablets a while ago, I got through them pretty fast. The most I tried was 8 tablets so 480mg. I thought I'd overshoot the limit everyone says your body can process just to make sure I got all I could out of them. It was pretty nice but I never found it that itchy even at those doses. I took two cetirizine tablets and only got slightly itchy. Tramadol on the other hand gets me itching for about 48 hours, no matter how many different anti-histamines I take. Although Tramadol itches are the nice pleasant to scratch type of itches :D
