I think I remember you talking about how intensive the treatments were when you looked into them in the past, Mari. It sounds stressful to me, and I don't know how anyone is able to work out transportation.
I hope you are able to find out about doc's med early today- one way or another. If you don't hear anything, I would call the pharmacy, your pdoc's office, or the insurance company before it gets too late in the day, so you can talk to your pdoc about getting a prescription for the Remeron, or something else you are comfortable trying/retrying like a Tricyclic...
I know that you want to adjust to your new medication before you have to return to work
