Suggest Remedy To Overcome The Withdrawal Symptoms Of Heroin

What can I take to get off heroine that isn t suboxone(sp?) Or methadone(sp?) And will help if not completely take away the withdrawal symptoms? I am an IV user, and have used for a number of years. I a Have kicked before, but always in jail. I want to stop, but I need something to take away the pain, or I just go right back to H. Please let me know if there is any kind of anything that will help the symptoms go away! Thank you!
