Yes they are. Hit me in my early 30's. Came on like a hurricane. Didn't know wtf was wrong with me. I was constantly worried about the health of my daughter and it made me sick. It felt like electodes were hooked to my head all night long. My head was just buzzing and I couldn't sleep a wink. Sucked. Klonopin will take care of that, but only if it's severe enough that you need it.
