If you weren't on a much higher methadone dose than 30ml to begin with it's not unheard of to swap straight to subbie. I've been on the methadone program twice now. The first time I reduced from 80ml to 30ml, went a few days without dosing and then swapped to suboxone. They started my suboxone dose at 1mg and the whole week of not dosing and then swapping to a low dose of suboxone was pretty rough. I remember going in for my first suboxone dose and shaking so bad that most of it ended up on my tshirt (it was a tablet not film, and crushed up on a spoon to deter diverting). I was licking and sucking my shirt like it was the late bit of opiate on the planet. Then my dose doubled each day until 16mg where I stayed even though I really needed to be on 32mg. I didn't feel right until I was taking 16mg for a few days. I ended up going from 16mg to 0mg in 3 days (I had had enough of being on the program, angry and frustrated). Needless to say it was very unpleasant, they were the worst withdrawls of my life and lasted about 2 weeks.The second time I went on the program I was extremely reluctant and only went as high as 40ml even though it was rough. When I reduced to 20ml they told me I could immediately swap from 20ml methadone to 1mg of suboxone. I ended up frustrated and angry again, and just stopped dosing altogether at that point. It wasn't so bad. I certainly wouldn't recommend such a harsh reduction, but I did it and survived, and now I'm over a year clean. It's totally at the discretion of your doctor and your clinic what dose they swap you on and when, my experiences were with 3 different sets of doctors and clinics. I see your post was a couple of days ago now, I imagine that you're through the worst of it. If not, just hang in there mate and don't worry, you'll be feeling ok again soon. I was also taking valium, seroquel, zoloft which I think helped me out a little, they should be giving you a little bit of valium at least. If not, ask for it. Best of luck mate.
