What drugs (both legal and illegal) make methadone wear off faster (so I can avoid them)? Or, just generally drugs that interact with it?

As the title suggests, I am wondering about drugs I should avoid while taking methadone. Someone mentioned that doing coke while on methadone makes it wear off faster, and another person mentioned that antiretroviral medications seemed to be the reason she needs such a high dose.

Just wondering if there are any other drugs like that to watch out for. I've been looking for a drug to take in a pinch to sleep at night, I'm not sure if taking zzzquil (diphenhydramine) would be a bad idea too.

Lmk, thanks!
