That is why he wants me to take it. To turn off my cns. 1/2 t 1mg in a.m. or as needed fr anxiety. Then 1mg at night. The daytime one is optional. He did not say for how long. He did say it has a 12 hour half life though so that it is not addictive. I don't know how much I believe that though as I see a lot of people having a bitch of a time getting off. I do have some valium, maybe I shouldtotoo tot try that, but I thought that was suppose to be extremely addictive. I am so bummed about last night. I don't know if changing the vitamin c is what caused it but doctor is suppose to call me back.
