You can find much information about CWE at: https://drugs-forum.com/forum/showthread.php?t=52325
I've seen it suggested that the water solubility of methocarbamol makes it a good candidate for CWE, but without tracking down more reliable information than I have, I would be very very wary of trying that. (Also keep in mind that the regular robaxacet has no codeine
at all. It is only the Robaxacet 8 that does.)
And regarding removing the caffeine
: filtering with activated charcoal. Look at this thread : https://drugs-forum.com/forum/showthread.php?t=54089
Since it is the caffeine you want to avoid, my advice would be to stick with the T1s and do the CWE and charcoal filtration.
Some of the symptoms of opiate
wd can be helped by taking loperamide
(Imodium) since it is an opioid
(though it does not cross the blood brain barrier). At the very least it helps with diarrhea.
