Are there any other molecules to try (I don't want to fall into Ativan and other benzos...)? Do you have any tips for Imovane withdrawal?

Yes, there are other molecules to try for insomnia that are not benzodiazepines. Some options to consider are amitriptyline, doxepin, mirtazapine, and Nozinan. Each of these medications has different benefits, so it's important to discuss with your doctor which one may be the best fit for your situation. It's also important to determine if there is an underlying cause for your insomnia and to assess your anxiety levels to find the most appropriate treatment.
