Like the others said, I don't think that it would work rectally. For me Klonopin (we call it Rivotril in The Bahamas), works pretty well for anxiety. The most I have ever taken has been 1mg as my pdoc prescribed it to only take as needed when I experience anxiety attacks. 5mg is alot to take in one day, atleast in my opinion. Just be careful with benzos, as they are very addictive, even though I take it now and again, it sometimes feels like my body gets very anxious without it.
