I stopped taking methadone two weeks prior to admission to hospital, but kept using fentanyl until the day prior to admission. I was so uncomfortable then they gave me medicine which shot my heart rate up to 212 and then gave me suboxone which made everything worse. I couldn't take it so I left. I may have multiple chemical dependency which may be the reason my withdrawals are so bad or that it seems like nothing helps.im scared to try it again, this wasn't my first attempt.
