I'm prescribed (for pm 15 years, serious injury) 30x100mcg per month (2x48 hrs) debt patch. I always get Mylan bc they're in an adhesive matrix and work way better than gel imo. (Plus I don't sound like I'm wrapped in Saran Wrap when someone hugs me) But long ago I started cutting them into quarters and cheeking them, changing patches out every 8 hours. About an hour after a new patch if I timed it right I might be able to sleep a few (3-4) hours. I have a very hard time sleeping. So what I would say, dopemaster, is that's the best effect I've found. Not recreational really, but you feel it a little and are otherwise highly functional. With transdermal ROA I feel nothing except pain relief (very slow onset though).
Just for background I'm a very experienced opiate user with a high tolerance, and also have tried every ROA with these except anal, with very little result for the amount of work - cheeking worked best. Cheeking def lasts longer than transdermal too. I was able to stretch out my scrip 150-200% using this method (again though, just for pain relief). These should be water soluble, no alcohols needed except tiny amount as anti-bac. Though I don't have a ton of experience in this aspect.
I know your OP was awhile ago but hope this helps. I just joined and friended you, because of previous posts you've written on other threads. I'd like to pm with you re chronic pain experiences.
