My question involves criminal law for the state of: Alabama

I've been an Ambien user for several years. Over the last year, I've started using too much and needed more than a "months worth" every month, so I've seen about 5 or 6 different doctors at different places to get scripts, a couple times with overlapping visits. I knew this was wrong in Insurance's eyes, so I haven't filed all the visits against insurance, but I've only recently started really reading about it and found out how illegal it is. I haven't been arrested and I don't know that I'm even being looked at - would there be a benefit to my talking to a lawyer before anything happens to me? What kind of penalty is there for something like this if I've never been arrested for anything? I realize I'm hooked on it and need help, but that's another story...
