Klonopin made me very sleepy when I first started taking it, but I was prescribed something like 2 mg per day, taking 1 mg in the morning and 1 mg at night. I complained a lot about the drowsiness and I believe it was reduced to just 1 mg at night. I don't recall that sleepiness bleeding over into the morning.

Nowadays I only take 0.5 mg at night, a small dose. I don't know if it does anything for me, but I don't have anxiety. When I do, I also have Ativan prn.I do not think that 0.5 mg even makes me sleep at this stage. I rely on Seroquel XR at night to help me with my sleep.
