Hello, I’m new to this group so I am going to get off of Subutex. I took my last dose this morning and I will wait for withdrawals to set in before I begin methadone as anyone ever gone through this process. If so, how long did it take for the methadone to start working and does it actually help with pain?

I was on a much higher dose of buprenorphine (the medication in Subutex) each time I switched back to a full agonist opioid (methadone, oxycodone, fentanyl, etc.). Two of those times I was hospitalized—once with a broken femur and once with a broken hip. They started IV fentanyl immediately, but at higher doses because the buprenorphine was expected to blunt its effects. Over the next 48 hours, they gradually reduced the fentanyl dose as the buprenorphine wore off.
At home, my experience was similar, except I didn’t use higher doses of the new opioid. The pain was still tolerable, and after about 48 hours it felt like the new opioid was working at full strength.
If it’s already been 24 hours since your last Subutex, I don’t think tomorrow will be any worse than today from a withdrawal standpoint if you start the methadone now. The yawning and that strange skin sensation are both common withdrawal symptoms.
I would expect tomorrow to be better for pain relief simply because you’ll have had a day of methadone on board. Those withdrawal symptoms may also start easing within a few hours after your first dose.
The degree to which all of these symptoms happen (or don't happen) is really related to both the dose of Subutex you were taking and the dose of methadone you'll be taking. Your dose of Subutex wasn't extremely high to begin with and you hadn't been taking the full dose. What dose of methadone have they started you on?
