Did you get off of it? They are saying in a Doctors Manuel from the Uk - The ashton manuel, that i longer acting benzo typically is needed to get off of a one with a short half life. Like colonzapam has 12-24 half life. They say valium helps in getting off other benzos because you can manage a taper easily being that there are not inter dose withdrawl symotoms because it has a half life of 100-200 hours or something like that. I want to get off Klonapin/colonzapam but they withdrawl symptoms are maddenin and so numerous in number an outsider would think those dealing with this are most likely just attention seeking but the fact is this drug should never even be given to people without very close supervision. They say 2-4 weeks is the longest they should be used and even then a taper is needed to come off of them so why would My doc perscribe this to me or anybody for more than the reccomended period? It's mind boggeling they would be so careless. They perscribed it to me for over 16 months and THEN I GET A message saying I cannot get any refills untill i see my doc. What a crock of crap. Seriously.
