Klonopin and little sleepy

I have been on Klonopin for over a year, with positive results.
Becacuse I did not make it to my Dr. app. last week, my doctor will not refill my RX, I have been told by three doctors that I have anxiety disorder. When I take my prescription of this medicine--- it helps with my anxiety. I take it as prescribed, which is 2 tabs of 1mg a day. I do not abuse my medicine. When I take it, I feel normal- with NO side effects, sometimes- it does make me a little sleepy....but I do feel so much better taking it, then with out it. More to talk about, but do not want to go on, and on about it! Thanks for reading! H. Clark in Washington
