i've taken clonazepam good stuff for anxiety try asking a doctor or google this
i believe it is safe to take them both, there should be no interactions between them.
the clonazepam should definitely relax you (it's a benzodiazepine, and that's what they do, careful though, it can be addictive if taken for extended times).
please keep in mind that i am no health professional, i only speak from my own experience, and the best info you can get is from a good doctor - one that would take the time to listen to you and answer all your questions.
best of luck
