Hi, Thank you for posting your query. I have noted your symptoms and found that clonazepam does not produce sleep in your case, after having used it for many years. Clonazepam belongs to benzodiazepine group and if used for long leads to dependence or tolerance. Thereby, it is difficult to come of them, and higher doses are required to get the same effect. So, you should switch to other drugs such as zolpidem, which are safer. Clonazepam should be slowly tapered and stopped. I hope my reply has helped you. I would be pleased to answer, if you have any follow up queries or if you require any further information.
