Hi celticfairy you might be able to get some help with this if you go onto the pain managment board, there are some people on there who have expirience of this. I myself am on tramadol but as yet have no expirience of coming off the drug, what you say sounds very similar to what others have suffered. I have heard very similar things about subutex/suboxone, also 13 years is a very long time and this drug seems to cause many, many unpleasent side effects, i have a friend who calls these symptoms post withdrawal syndrome which may be what you are are suffering. If its any consolation everyday clean is a day further away from it, recovery from narcotics is a long slow process unfortunately but your doing excellent give yourself a big pat on the back and keep posting theres plenty of support on the addiction and PM boards.
