Amazingly low tolerance!

[finriswolf]

After reading many, many posts (very good and informative by the way - Swim loves this website!) SWIM has come to the conclusion that he may be an extreme lightweight when it comes to opioids. After over a year of daily usage with doses never exceeding 10mg but most often at 5mg SWIM still gets the desired results (the relief and possitive side effects). But SWIM constantly reads posts about .30 .60 .80 120mg usage that are just not enough for those SWIMs. IS there a biological factor involved here? SWIM does not drink or use any other substances (other than OTC pain relievers) so SWIM cannot compare tollerances with other substances. Can someone explain why SWIM after a year, still has a good result with such low (compared to most on this forum) dosages?
