New here:) how to potentiate methadone?

[MMT/$@V3D/M3]

Hello everyone!! I have been getting information from this site for years anytime I have a question about my medication or what's ok to take with it I would type in Google and find a thread that related to what I was looking for. I decided to register so I can ask Questions myself or even help someone else that I may be able to help. My question today is what is ok to take to potentiate methadone? I just learned about too much acid being in ur stomach when u dose that u won't absorb ur whole dose. I've read different things here and there but not sure what to try, anything that might help plz let me know. Just trying to get the full dose absorbed, I used to drink 2 cups of coffee in morning before dosing, now I wait til it kicks in. I'm 26 female, I go to the methadone clinic I'm on 90 mg.
