Hi. Yes you can ask your doc for a particular med. It shows that you have done your research and are taking a proactive role in your own recovery. If your doc has a problem with it, then he/she has a problem and it might be time for a new doc. They should be open-minded to any feedback and suggestions. They don't know what will and won't work for you. They are just guessing. My doc is great. We work together on my treatment plan. I quite often go in there with suggestions if I need to change meds. He loves it because it makes his job easier and shows that I'm committed to doing the right thing med-wise. He sometimes gets stuck for ideas because we have tried so many different things, so any help he appreciates. I talk to mainly american people on here and some of their meds have different names, so sometimes I will go in there asking for something I have heard of on here. He will then look it up, see if we get it and decide if it's suitable. He also knows I'm open-minded about trying brand new meds and trying different combinations, so this makes our choices much wider.
The Ad you take is pretty old school. Maybe you could try a newer one. Why are you on seroquel and zyprexa? I thought they both did the same thing. Weird. Two AD's which have worked well for me are Cymbalta and Effexor. They both took effect quickly and both had minimal side effects. They both worked well for approx 2 years, then just stopped working. I'm currently newly on Pristiq, which apparently is a more refined version of Effexor.
I hope I've been of some help. Good luck, take care and keep us posted on your progress and any other developments.
Just repeating, be assertive and proactive when it comes to your mental health and treatment. You are your own best advocate. You know you and what feels right. Don't be afraid to speak up. And anyone who makes you feel bad for speaking up is not the right person to have in your life.
