Tolerance and weight both play a big factor in the dosage. Also watch out for your intake of acetominphan(sp?) as high doses of that can damage your liver. I would go for a 150-200mg dose, so drink around 30-40ml.
The first opiate I did was Codiene (T3's). For an introduction to opiates its not bad, but they are definitly way better opiates to enjoy. Smoke a little weed too, that always seems to amplify the effects for me.
