I'm starting 1 mg. clonazepam twice a day today. The docs classify it a benzo like lorazepam(ativan). However, they also say that the clonazepam takes time-maybe weeks-to work into your system, it's not fast acting. The docs also say that clonazepam works more effectively than lorazepam because it's effects are longer lasting. Does anybody know if this info is true or false. It may depend on the person, so does anyone have any experience taking this anxiety medication clonazepam? I'd like to know how long it will take to start affecting me. Will it be weeks, months or what? I strongly suspect that my doc is giving it to me because it's not as strong or addictive as the other benzos. I just hope it works, I'm quite tolerant to benzos, having been prescribed librium at one time, and thorazine at another time. Based on these facts, would 1 mg. clonazepam even affect me at all?
