Hiya, I am prescribed both, 0.5mg clonazepam around 25 a month and 2mg diazepam 15 a month. The only real difference I found is tolerance, after taking a diazepam for a few years at a low dose semi regularly, clonazepam seemed to work alot better, but I do think it was because it was new. Now I alternate between the two when I need too. I find that helpful because I can stay at a low dose of both and they work just as well for what I need. The only real way you'll know is by giving it a go though, medicine's work so different for everyone involved. I hope you find something that helps you!
