Gabapentin
"For the last 7 years I have had severe anxiety, panic attacks, and insomnia. I was given remeron for sleep and klonopin for anxiety. Recently my pdoc and I decided it's time for me to get off the benzos. She gave me gabapentin and it's been a life saver. I'm doing well at gradually tapering off klonopin. The only drawback I find is that gabapentin wears off rather fast, and your body builds up a tolerance really fast. Been on it for 3 months now. I started at 100mg 3 times a day. Within a month I was up to 300mg 3xdaily and 600mg at night. Currently I am only taking it PRN at 300mg. As someone who has tried every mood stabilizer and anxiety medication  under the sun. Gabapentin is amazing!"
