After taking Clonazepam, my anxiety lessened and i found myself able to sleep more deeply and easily. I take upwards of .5 to 1.5mg at nightime to sleep. Itr calms me down and at times, can make you feel a little euphoric. I wouldnt say that the euphoria is a negative side effect but, some otehrs might view it as such. Enjoy sleeping and living a relatively anxiety free life.
