Klonopin is a benzodiazepine (benzo) medication. Clonazepam (Klonopin) starts to work in 1 hour and the effects lasts
6 to 12 hours. Benzos like Klonopin relax you. The side effect is that Klonopin and other benzodiazepines can become habit forming and even addictive for a while. Klonopin is good for anxiety and works better when combined with
propranolol.
Propranolol is not addictive so it safe and you can switch from Klonopin to Propranolol. Do not mix Klonopin with alcohol, or you will likely black out and do something stupid.
