Newbie here

Thanks to a close friend of mine who is currently battling issues with Klonopin (Clonazepam) I am beginning to realize previous issues I faced may have been Klonopin related.
I am also very concerned about some seriously abnormal behavior in my elderly mother who is also on Klonopin as a part of her Parkinson's cocktail.
Please, any information or helpful links would be greatly appreciated. Specific concerns are: behavioral differences, differences in the ability to make rational decisions and the infamous withdrawal problems. Thank you so much in advance!
