I need help, the doctor prescribed fioricet (well the generic, says bitalibital/apap/caffeine tabs. It only says take one tablet by mouth as needed. HOW OFTEN can I take them??? Does anyone know? I know they have tylenol in them which means I need to be careful not to overdose on it and kill my liver! I've been up most of the night, it isn't doing much for me at all. I plan to call the doctor as soon as they open. I have wrote down exactly how I've been feeling, what I've been feeling, and all that. It went down into my neck/shoulder and had my boyfriend rub my neck with linament thinking the migraine was making my neck muscles tense up. It was so painful I thought I was going to pass out, went down my right arm like  a live wire. I had him stop right away. When I lay down the pressure is huge in the right side of my skull. Sitting up its a little less but the orbit around my eye still hurts and the aching in my skull is still present. My vision is being assaulted too. All this because I tried to eat a dumb hot dog yesterday. <sigh> No more of them!
