I'm on fiorinol and fioricet for migraines. I take them cuz I can't do the triptans and they work for me. When I first take one I get a huge rush, get talkative, feel more open, friendly,happy. I have NEVER taken one for anything other than an actual migraine, but I find myself fighting that temptation everyday. This sounds nuts, but I literally pray to Jesus to give me a migraine so I can take a pill. The only other substance I've been hooked on is smoking, but I've been quit around 8 yrs. I fight that temptation everyday too. Side note - I'm bipolar with anxiety disorders
