So thankfully my opiate tolerance is quite low, I've only done codeine so far and only take 90mgs to get high, so would 50mls of Rikodeine do the trick? And how bad would the sorbitol effects be at that amount?
Some people consider dihydrocodeine to be stronger than codeine, so you might not need to take as much. The other ingredients in the syrup, like sorbitol, can disagree with some people, so probably best to start low.
