Hey
@Opiatelover7423 Thanks for the kind words. I'm glad I've been able to help.
Here is the thing. Methadone is not as subjectively "good" as Morphine. There is a whole textbook of science I'm not gonna try to unload on everyone right now. Suffice to say, there is a preference. However, Methadone itself is "good" in its own way. If I had to try to quantify it, it's like 75% as good as Morphine/Heroin. What I'm driving at, is that it is possible to stabilize on Methadone without any other Opioids.
I've been at points in my life where I've injected 3-4 grams of Heroin a day. That's extreme circumstances. Still, my lifetime use was ~2g every day for ~12 years. I tried Buprenorphine. It was not a good situation. It made me feel like I was locked in a stasis. I couldn't use Opiates due to the blocking effect. The problem was that I was still craving Opiates BAD, all day every day. I was somewhat stable, physically speaking, not dopesick. The cravings were unreal though. It did not sate my cravings. I was like a starving guy who couldn't eat food.
Methadone was different. Once I got on a high enough dose, I didn't crave Opioids so much. Cravings can be this primal, visceral feeling like sexual lust, where your whole body and mind are dragging you toward dope. My cravings now are like memories that I'm able to understand without those intense feelings. I remember it felt good. I know that I want to feel good. Basic logic tells me I should use Heroin again. When you're on the right dose of Methadone, you're satisfied. You don't want more Opioids.
That is the goal I feel you should be working towards. You might need more Methadone. There would be nothing wrong with you going up to 80mg Methadone and see how you feel. I truly believe that when you get up to the right dose, your cravings will be much easier to handle.
When I've been on Methadone maintenance, I've never actually been able to get "high". I've injected large amounts of Heroin; my nose itches for a few minutes then I take a nap. That's great if you want to take a nap, though you could get the same effect by taking a few Diphenhydramine (Benadryl) or what have you.
Basically, the effects of the Morphine will be heavily blunted by the Methadone. You are unlikely to get where you actually want to be. I consider taking other Opioids with Methadone a waste of time. I know some people use Fentanyl to "break through", though that seems to just entail an immediate, unconscious stupor for 1-2 hours followed by a return to consciousness.
You are your own man. I can't judge you for wanting to experiment. I'd start by just taking your normal dose of Morphine. If that doesn't work, you can up the dose after 45-60 minutes. I'm telling you as a friend looking out for you that this practice is a waste of time, money and doesn't help you in trying to fix your life.
Again, I understand completely. Do your experiment and see how it is. You're unlikely to overdose, especially considering your cautionary approach. I would advise trying 80mg Methadone for a week or two.
