I'm not sure what APRN exactly stands for, though if it is Advanced Practice Registered Nurse, then I quite honestly would not be taking what a nurse is saying as valid about medication. Even doctors, whilst they do a year on them, the simple fact is, you need to speak with a good pharmacist... these are the experts on medication, and the only people you should ever really turn to when looking for quality solutions based on your history.
You have a doctoral degree taking 4 - 6 years, then a pharmaceutical degree taking 4+ years. A pharmacists does nothing but pharmacy... I would seriously see one vs. trying to nut out solutions specific to you on a forum. I don't know about where you are, but in Australia, you can speak to any pharmacist free of charge by visiting a chemist (drug store I think you call them in the States). I would presume the same is applicable their!
This is the problem with the medical industry... doctors handing out pills left, right and center, but a pharmacist can often give you far better solutions and whether or not a specific pill is best for you, dosage, use, etc. Doctors often follow pharmaceutical companies guidelines, pharmacists often know better, with greater experience, especially when mixing medication.
