First time with methadone--how much to take?

[Adormidera]

So I have the chance to try some methadone today, which I've never been super eager to try, but I'm out of morphine, and pod tea and Vicodin is getting old fast, and I still have almost two weeks to go. So the methadone is looking pretty good right now.

I gather that it's not really worth shooting it, if not an outright bad idea. So if I take it orally, how much should I take? My usual habit is about 6 of the MS Contin 30mg pills daily, IV. I don't know exactly what that equates to in mg's because of the sustained release thing. I don't want to overdo it because I have to go to work tomorrow and be functional. But I want to avoid withdrawal and get decently high if possible.

I am thinking maybe 30-40 mg?

Any advice?
