I'm prescribed to take .5 mg at bedtime and .5 in the morning because I suffer from anxiety. It's not so much anxiety, but I'm high-strung. I'm also given extra klonipin for PRN if I have a panic attack. I noticed if I take more than 3 mg I get shortness of breath. I feel like my breathing is restricted. I never experienced a seizure however. All in all Klonipin has been a very helpful medication.
