guys, iv read thru this post and i consider myself fairly experienced with codeine use, (not too much though

) and i just have a couple of things too say
iv read a few posts about people saying they have CWE'd n+ and it still appears cloudy and other people telling them they are not doing properly
anyway from my experience, n+ WILL filter a cloudy white colour, almost like milk. im guessing this is the slight amount of ibuprofen disolved in the water that causes this.
i normally use panadeine for CWE's and they filter clear with a slight white tinge. all the people have trouble with n+, give panadeine a go. i also notice the yield i get from panadeine seems to be higher than that from n+. the ibuprofen and binders in the n+ tend to go alot more gluggy than those from the panadeine.
i also dont crush the pills, just leave them in water until the dissolve, stirring ocasionally. iv noticed that panadeine disolve fairly quickly this way, about 10 minutes. codalgin and n+ take a whole lot longer.
also go down to ur local supermarket and buy some coffee filters, they are dirt cheap, like a dollar for 40, put it in a tall glass and fold the edges over the edge of the glass, and if doing a large load put a rubber band around the outside to stop it sliding in (it will if u do a CWE with alot of pills).
have fun and be careful.
