Darren,
I have not experienced your symptoms and am very sorry to hear that you are going through this. The only thing I can offer you is research, research, research ! Those of us in the AN community must bcome our own proactive advocates. I know I drive my treatment team nuts but I am a very active participant in my treament. I never take things at "face value" and try to dig to the bottom of any aspect of my symptoms or the suggested treatments. If your current crew simply ignores the problem and tells you to learn to deal with it, I'd be looking for another crew. Ultimately, that may be the only choice but there is simply no reason to accept it without doing everything you can to find a solution. There are many excellent web sites that allow the public access to medical journals and other quality research type information. So, read, study, research, and talk to your treatment team. If they won't talk, find someone who will.
Richard
