I genrally consider Ativan to be less potent then Klonopin. Also flonazepam is a short acting benzo while clonezapam is a long acting benzo. It would probably be best to stay on the Klonopin mainly because short acting benzo's has had a larger correlation with seizures (when suddenly stopping them) then long acting benzo's. But whatever floats your boat , if it helps.. it helps, I say try it. Peace, Bromo
