Yes, I had a friend that took klonopin for severe migraines and stress related issues. She slept all of the time until she became very depressed. Weed would definately help your mother wean off the klonopin. It is important to let your mother make the decision to come off klonopin. I am unsure of her diagnosis or why she is taking it, but I know that weed has many anticdotal properties and helps resolve a lot of symptoms. Klonopin may not have depression as a side effect, but studies have shown that people who tend to sleep a lot during the day due to medication have depression. They battle low self-esteem from their sleeping habits. They just can't stay awake and then feel guilty. Have you tried talking with your mom about your concerns? Is it safe for you to discuss this with her?
