Took those together to months. Didn't have any breathing problems. Olanzapines sedative effect for me only lasts for maybe 6 or 7 hours. I never felt sedated during the day at all on it. And no benzo seemed to make my breathing worse(unlike when making with certain other mental health meds)
I don't know the answer, but I have read the augmentation studies on the NIH website and this isn't the way to do them. If you take a medication and it doesn't work, as you say, you don't add another med to it, you find another med that works. You only add to a med that's working but not well enough. Do you have a psychiatrist or a regular doc doing this? Also, is anxiety your main problem or is it caused by depression? I ask because if anxiety is the main problem wellbutrin wouldn't be a drug to use, as it's the most stimulating antidepressant out there short of taking speed. There may be good reasons for what's happening here, but I'd want more info if I were you. As for your main question, I'd check the website of the manufacturer and some of the better more reliable sites such as Mayo Clinic and NIH. Asking a pharmacist is also a good idea about contraindications and how often bad reactions might be happening.
