What Is The Ideal Time To Take Klonopin To Manage Anxiety?

I take klonopin 0.5 mg at night for anxiety. What time of night should I take this to keep me from being tired during the day but enough to give me coverage throughout 8 hour day. Should I take half dosage at night 0.25 and then later in afternoon take 0.25 would that make me less sleepy?
