Whats the codeine concentration?
Each pill is 30mg codeine 500mg paracetemol.
Yes.
How many pills should i take to get a feeling.
a CWE on 7 pills (210mg of codeine) would be a good starting point.
Pretty much just need the rundown on how to do it.
It's incredibly simple, ignore all the complicated guides on the internet about refrigeration and so on.
Take the pills, put them in a cup, add enough cold tap water that it comes up a CM or so over the pills, wait till the pills break down completely and you have a cup of water with powder floating in it. Stir it a bit if you need to. Now get a piece of cloth (a cut off section of a button up shirt works well), place it over another cup with an indentation and hold it in place with rubber bands so you can pour the water with the dissolved pills into it (alternatively, use a coffee filter, but this is slower and you get a lower yield). Pre-dampen this filter so it doesn't soak up the codeine, then pour the water with the crushed pills into it - the water should drip through the filter, while the solid powder which didn't dissolve should be caught in the filter.
Once there's nothing but powder in the filter, run a bit more water through it and then pick it up and squeeze it to get the water stuck in the powder all out. Now you should have a cloth filter with a pile of gunky paracetemol in it and a cup with water which is clear or slightly off color but, and this is important,
does not contain any solid powder. The coloration of the water is due to the dyes in the pills and the small amount of paracetemol which dissolves (less than a regular 2 pills dose) and is fine, any solid matter is not fine and means your filter either broke or wasn't tight enough.
Now drink the liquid and throw out the paracetemol gunk, then sit back and enjoy. I suggest you take a low dose (1/4 or 1/2 pill) of doxylamine succinate (Restavit, sold at the chemist as a sleep aid) 30 minutes before drinking the codeine, this will prevent the nausea and itching codeine causes as a side effect.
Don't thank me, you'd be better off just throwing the pills out.
