... so their is no tolerance? For 6 months my anxiety has been constant every single day. Not panic attacks just constant anxiety it really sad. My Dr. has put me on 40mg of Prozac I'm now on week 9 its not helping. He has put me on gabapentin, hydroxyzine, Buspar on addition to the Prozac but none has helped with the anxiety. He finally prescribed 0.5mg Klonopin. I took it this morning because anxiety was bad and it nothing but make me sleepy did not touch my anxiety. I've not sure what else to try. My anxiety is so bad and will not go away I have it 24/7. Before my anxiety was like waves that came and went threw out the day and Paxil had worked to control it. Has any one had anxiety that was constant and did not go away. I don't want to believe that I have to live the rest of my life like this I'm only 47 years old. I can't live like this. Help anyone.
