Have everything written down. All the symptoms, all your concerns, all the background info, anything that will help the doc evaluate you.

Its so easy to forget important bits of info when you start getting deep into a session. You might forget to mention something that could be a key for the doc to properly diagnose you.

Take notes during the session so you can keep track of the docs suggestions. Its also helpful to keep a daily journal so you can track your own progress.

Best wishes and good luck
