Ouch.....that's a difficult situation to be in ((((((((((( unpredictable )))))))))
Would it be possible to go back to your MD and explain the situation to him/her and ask for help until you get to see the pdoc? If your MD has your records from the last pdoc, he/she can even phone your other pdoc for info if needed to help you with your med issue. Once in to see the new pdoc, your MD can then stop prescribing.
I sure hope you get in soon to the new pdoc....things like this really boggle my mind sometimes *sigh*
Wishing you well!
