Hi I used to have co-codamol 30/500 in the form of Kapake or Solpadol. I build up tolerance and would take 3 of these at a time and sometimes 4. I could handle these well however I was concerned about the amount I was taking due to all the paracetamol. I managed to get the df118 40mg tartrate prescribed which don?t contain paracetamol. Are these stronger and longer lasting? Would I be fine to take 3 of these at a time? Thanks.
