In this state (Indiana) it's against the law to drive in an impaired condition. While this never seems to apply to age or stupidity it does apply to sleepiness or any condition or medication that might affect your ability to drive. You should try a new medication before you attempt to drive under its influence. You should also never suggest there was a problem with your condition if you're pulled over or have an accident.

I've been on a large number of medications and none except methadone really had any effect on my percieved ability to drive. So I simply didn't take the methadone and then drive. It's not that I was stoned, sleepy, or distracted on methadone so much as I just didn't feel fully in control and didn't take things as seriously as usual. I've never driven like my day depended on it; I drive like my life depends on it.

But you're not going to get charged in this state for anything like this if you can act straight and pass a breathalyzer unless you suggest it wasn't your fault because you were stoned or under the influence of an overriding condition.

I'm not as competent a driver as I once was because of the RSD but I've simply adjusted by being more cautious and leaving more room. I might be less likely to have an accident now. I'm sure I'm far less likely to have or cause a serious accident than I was.
