about to quit again (for the last time)

i first started taking percocet 5mg when it was prescribed for me about 2 years ago though a dentist last year and for knee pain my addiction got so bad I finally decided i needed help unfortunately I have medicaid so its very hard to find places that will take me for detox I finally found a place called Bayshore hospital in nj where they pumped me full of fluids and unfortunately put me on methadone so when I was released from detox i was referred to a methadone clinic which made me veryyy sick because of the psychiatric meds I am on so i had to go into another hospital to get off the methadone and get my meds straightened out after 2 months of being in the hospital I was released for months after I had horrible cravings but they eventually went away I got through the cravings by thinking about how bad my addiction was and thinking I didnt want to go med seeking again from hospital to hospital. a few months ago I started having alot of dental work done and thought to myself ok if I am prescribed the percocet I wont go back to the way i was which was sooooo WRONG,now i am back to where I stared and when i got another prescription a few days ago for 30 pills i thought ok this is my time to taper myself off not knowing just how strong my acciction was,now 5 days and 29 pills later I am scared knowing in a few hours my cravings will get very bad and that I need to seriously resist them,I really dont want to go back into the hospital unless i really have to and want to try to do this at home like (sadly) I see alot of other people on here trying to do I wish you alot of luck and my prayers will be with all of you and please dont lose hope and give in to this horrible drug there IS a way out of this I have done it before and I will do it again for the last time!
