I UTFSE but to no avail WRT soluble tablets. Its a very basic question, even for the "Newbee forum"....
Having read

the process of seperating codeine and caffeine seems pretty simplistic. However, due to "ease of procurement", I am thinking of using tablets which are soluble. They contain 500mg paracetamol, 30mg caffeine and 8mg codeine each. The scale would be involving 3~5g of codeine, so several hundred tablets.
Would just using a smaller amount of water be enough, to prevent whatever mechanism they use to dissolve the paracetamol from working, or would there be need for a more complex extraction, such as the acid/base method talked of here :

I've done CWE before but not on soluble tablets. If push comes to shove I can use the non-soluble brands but they come in smaller quantities, so more hassle getting enough packets to be practical.
Thanks
