Honestly, if I were you, I would talk to your doctor about how your insomnia affects your daytime anxiety.
After speaking about my insomnia problem with numerous doctors, I finally found a doctor (after about 4 doctors and 12 months of searching) who
would script me ambien, but it was only 5mg/day. After about 6 months, I got that increased to the standard 10mg/day.
Then, one day, I brought up how my anxiety and insomnia correlate, and yadda yadda yadda, I also got 1mg klonopin/day.
If you legitimately have these problems, then it's not hard to get the scripts from a doctor.
The issues arise when you are "pretending" to have these problems, and at that point, you are just playing an act that is hard to believe.
Don't even act like you're trying to convince your doctor, because you legitimately have these problems.
Just tell him what the problem is and what you are comfortable/uncomfortable with taking.
