Thank you for your replies. Yes, my doctor knows about the meds I am on. He is slowly tapering my off the Fioricet. I do know that the "cet" means Acetaminophen is in them, and that is a major concern. I get my blood checked often, and 2 months ago was my last check. All was ok, including my liver. So that is not the reason for my weight loss, thankfully.
Anyway, I know that my doctor should know all of this, and until recently I was afraid to tell him. But now that I did I feel hopeful that I will be able to taper off the Fioricet. However, I was just curious if any of you have experienced weight loss from Fioricet.
