hi everyone, i've never posted in any kind of forum, but searching for info i found an old thread from this site and there were a lot of well-informed people sharing their insights, which i could use right now. i consider myself well informed as well, but i think i need all the help i can get right now. i was going to a methadone clinic, on 90mg. I had my last dose sunday night/monday morning. It's now friday. I've been using heroin to stave off the withdrawal. the methadone has a long half life, but i think it should be effectively out of my system by now. i haven't used dope since yesterday and i have no symptoms of withdrawl yet. i don't plan on doing anymore unless i get symptomatic, i just sort of assumed i'd be in withdrawal already. I have suboxone and xanax, i'm just afraid the suboxone won't work- thats why i went to the methadone clinic, the subs stopped working for me. I also get severe withdrawal symptoms. I know the conventional wisdom is that opiate withdrawal is never fatal, but i have other medical conditions that seem to make my withdrawal worse. Every addict friend i have says they've never seen anyone get as sick as me. once the wd's start i start vomitting and don't stop. i don't sleep, i am in no way functional. after two of three days of (literally) nonstop vomitting i end up in the hospital, and then usually on a heart monitor because all the vomitting has depleted my potassium which can lead to heart attack. because of my other health issues that make me a frequent flier at the hospital, i don't want them to know about my drug issues, so i don't tell them i'm in withdrawal and they give me iv dilautin (sp?) until the vomitting stops, they send me home and i'm right back where i started, and the torturous 2-3 days of vomitting were entirely pointless. i obviously want to do this differently this time, i'm just terrified. and confused- why aren't i sick yet? any input, advice, info would be very much appreciated. thank you in advance to anyone who replies:)
