What is your Temaz dose? Typically it is 15-45mg, some people of course take more, although more than say, 2 capsules, or 75-90 nightly, is uncommon
Alochol is a no go - Codiene, really hard to recommend, although it is the one opioid, you could mix a moderate dose - Always start small, you can take more, yet rarely less
