hey,
i'm so glad you are here and posting on this site. that is huge. congrats on trying to get clean, all it takes is some willingness and some effort on your part. first, you really should be talking to your doctor about all this to figure out if you need tapering. you said yourself you cannot detox alone, tell that to your doctor!
also, i really would suggest getting an NA meeting list for around your area and get yourself to some meetings. going to meetings helps reduce the obsession part of my addiction for me, and there you could also meet helpful people and make sober friends. you need as much support as you can get!
please stay in touch. there are a lot of people on this site who can offer you dopesick help, plus come into the chat section for immediate, live assistance!
i never shot oxys but i was doing an 80 everyday (along with copious amounts of other drugs) and the only thing that really helped when i got sick was a warm bath and gatorade.
good luck & stay safe!
