Hi Steve,
Are you trying to decrease the dosage of Klonopin on your own? Seems a huge difference between a dosage of 8mg a day to 4.5 mg a day. Any type of adjustment in medicine has to be taken up gradually, and the sames goes for coming down on it, you have to be weaned slowly and just as gradual. If you are doing this on your own, you are probably experiencing too much of abrupt withdrawal symptoms, and can be dangerous.
As far as SSRI's they have helped me tremendously, as it directly affects the serotoin we need in the imbalance of the neurotransmitters in our brains, true benzo's like Xanax and Klonopin, are good for the more immediately relief of panic or anxiety, but it in the long run, doesnt help near as well as the SSRI's does with agoraphobia. When I first started mine, I was more panicky at first, but my agitation eventually subsided within a few weeks, and I noticed a remarkable difference, and felt more energy, no more sleeping all the time, and helped me to work on getting out of my agorphobic, I was able to work on my exposure therapy. But my doctor had me on the same as you, SSRI with conjunction of the Benzo, starting out, that once I got enough of the SSRI in my system to help suppress my attacks, we could wean me off the benzo.
