Welcome to Sober Recovery. I'm not familiar with Fioricet, but I am familiar with drug and alcohol addiction.

Too soon for Post Acute Withdrawal. You are still in initial withdrawal. As for the way you feel, I looked at those feelings as my addiction's way of making me long for the "old" days that taking my drug would revive.
I've learned a lot in the four years since I relapsed on Hydrocodone. The main one is this: I'll take a gray day clean and sober before I'll take a drug-induced "happy" day. And a "happy" day clean is REAL!
Good luck.
