Clonazepam
anxiety
"Indigogirl,
Switching from Ativan to Klonopin is very common. Due to the fact that Klonopin is 2x more potent tand lasts much longer also. 2mg Ativan = 1mg Klonopin. Ativan has a 12-18 hour half life, while Klonopin has a 24-50 hour half life. Ativan peaks within 30 minutes, while Klonopin peaks within 2 hours. If you were too sleepy with the switch, your Klonopin dose was too much. For me, Klonopin is the best all around benzo. I've been on Xanax, Ativan, and Valium, Klonopin is the king of the class of Benzodiazepines."
