Yeppers! I have that same issue... urr... Hyperarousal can stink. I hate it when my ears "pop" at any sound at all!!! Do you ever have that?

One thing that may help you is valarian root. It is calming. The other thing my T suggested is 5HTP. I have taken that now for 3 days and I think I am feeling less sensititve maybe. Will see once I get back to work! LOL
