re-dosing question

[sivoodoo]

Hi all,

SWIM took two co-codamols (30mg codein 500mg Paracetamol) and one Dihydrocodein tablet (30mg) total 90mg codein/1000mg paracetamol. SWIM said he got the high he wanted but this fell off after a couple of hours and wants the same effect! How long should SWIM wait as I have heard that re-dosing too soon will not work as codeine inhibits the enzyme that turns it into morphine in the brain.

If SWIM was to take two dhydracodeine and two co-codamaol after say 3 hours of the first dose would this be worthwhile or should a longer period between doses be had?

SWIM suffers back pain and has also been prescribed diclofenac but does not take these are they sound full of crap!

Thanks
