In December, I stopped vicodin cold turkey and have never looked back (well, maybe a few times I peeked!)... Anyway, my doc Rx'd fioricet for headaches recently and I only took them for about 3-4 days until my head was feeling better... Well, here's my question. I feel like I am withdrawing from opiates all over again! Nausea, heart palps, weird sensations in hands, muscle twitches, etc etc... Could this be from just a few days useage of fioricet?
