MarleyCat, I just wanted to let you know I used to see a pdoc who did some similar things. I had awful insurance at the time and I was going through pdocs so fast because they were all not for me (perhaps not for anyone, actually).
This particular pdoc would not listen to me when I told him that the antidepressant I was on was causing bad side effects. He didn't believe one was causing me bad nausea even after I threw up in his office bathroom. After several appointments I put my foot down and said I NEED a different medication. His response was, "What medication would you like to be on?"
I said, "I don't know, I'm not a doctor, how am I supposed to know what medication I should be on?" He seemed annoyed at my response and started flipping through his Physician's Desk Reference and listing different meds and asking if I wanted to be on each (without explaining any differences, possible side effects, etc.) Not terribly confidence inspiring.
I DO appreciated pdocs who value patient input. There have definitely been times when I don't want to be on a certain medication for some reason. But what is the point of the doctor if they basically want you to write your own prescription?
Luckily I was able to get better insurance and find a better pdoc later on. My advice to you would be to try to find someone who has a style that suits you. I would also suggest you do do a little research yourself on meds just so that you are informed and prepared.
I hope things work out for you!
