Taking other medications in addition to antibiotics for NTN

I have NTM and am on a daily regimen of azithromycin, ethambutol and rifampin. I also have COPD and long covid with severe constipation and GERD. I also have high anxiety and depression. I am struggling with when to taking different medications. I take azithromycin and ethambutol at 5:30 PM with dinner and rifampin at bedtime. I am not able to take PPIs and pepcid and depend on PRN medications such as mylanta, miralax and fleets enema. I am also on Cymbalta for depression. I know that the antibiotics need to be spaced out from the other medications. Any suggestions to help with this schedule would be appreciated.
