According to the DEA, a schedule II controlled substance is less detrimental to society than marijuana. Although I agree with the majority of posts to your question (you need a lawyer), I think they're answers are more fearful than helpful. The chances of you spending 4 years in jail of schedule II possession are about 1%. You would likely have to of committed a crime substantially more illegal in ADDITION to the possession to spend 4 years for it. We're talking something like rape, murder, etc. The reason we have maximum sentences in law books are to A) appear to be harsher penalties B) discretion of punishment.
Let me elaborate on discretion of punishment. Say you have a child molester with possession of a schedule II. Versus yours with the DUI/OWI. That child molester will get a stiffer penalty for the possession than you even if it was essentially the same exact crime. You will more likely get a stiffer penalty for the operation of the vehicle. But they're going to put a guilty child molester behind bars as long as they possibly can. The judge's job is to make sure you learn. And trust me, they know humans will never learn not to use mind altering substances. It kind of falls along the lines of the need for information. We as a whole are gullible in that aspect and this is well documented medically and legally. Judges know this.
So, get a lawyer. Most that's going to happen is probation, a fine, community service and/or restitution for the sign. Possibly ALL, so be prepared for that... it won't be cheap. But jail as a first time offender. HIGHLY DOUBTFUL!!
