Hi bpcyclist. I have never taken Thorazine, but wanted to send a few sheep to count your way, in hopes that you do get some sleep tonight. I have taken other 1st generations, but not sedating ones. Out of curiosity, can you put your finger on some of the main reasons you can't sleep? Racing thoughts and/or extreme energy levels at night, etc? Have you tried combining this new tool with other sleep hygiene tactics? I'm talking, really bombard the insomnia from all angles. Sometimes that is what it takes for me, when I'm manic or very hypomanic and even higher doses of my Seroquel XR (or added regular Seroquel or Ativan) don't fully help.
