SWIM's nasty fentanyl experience and some ?'s

[skinnykitty]

So SWIM got a hold of some 50 mg fentanyl gel patches and decided to apply one patch. She felt really good for about 24 hours, and then proceeded to become violently ill and scared. SWIM knows this is gross, but SWIM was throwing up many times and then began to puke this yellowish-green nasty-tasting slimy substance. Can any SWIY tell SWIM what this was? Certainly not something SWIM ate...

Anyway SWIm had to remove patch and is freezing in case there is any way to administer the fentanyl in smaller doses. Can SWIY help SWIM with coming up with some ideas? SWIM hates the idea of wasting opiates. SWIM thanks you in adavnce.
