I have just had his tonsils out and has been given a load of 30/500 co-codomol pills, and has just bought some Promethazine as he found it really hard to sleep last night due to the pain. I have never used any sleeping aids before and just did a quick check to see if Promethazine had any recreational value which it seems not to unless combined with codeine. Does anyone have any info on how the two combine? Does it simply potentiate the codeine and make it stronger? Also I have dropped a couple of piperazine pills (mint wicked highs) today and was wondering if codeine is OK to combine with them? Hoping this Promethazine is good as SWIM always finds it hard to sleep after BZP.
