Few years ago i was in similar situation. Waiting on disability w no insurance. My dr and i tried just about every combo out there. Now that i have insurance, I presently take Opana extended release along with oxycodone instant release......when i didnt have it i took Oxycontin extended release with Oxy instant. Same med, just controlled and instant release forms. Worked better than anything else i had tried. Maybe give that a try? Fentanyl can really be bad news!!!!
