I need help finding a decent fentanyl matrix patch since Sandoz and Teva are unavailable. Thank you?

My question is about the availability of different transdermal fentanyl patches. I'm aware the gels are now unavailable, which I've never tried anyway. I've always used the matrix and have had problems in the past with certain patches not lasting 72 hours. Until I used the 50mcg sandoz matrix patch which worked great and now they've been recalled or something. Ive also heard teva is unavailable also. I'm using Mylan which is definitely not lasting 72 hours putting me in...
