"i&#039;ve been using gabapentin for anxiety along with lamictal for bipolar type 2. before the gabapentin i was on vistaril. i didn&#039;t like the way vistaril made me feel during my attacks and gabapentin has made it so much easier to manage throughout the day and even the attacks aren&#039;t as bad. i also have ptsd and it&#039;s made it a lot easier to function. i take one 100mg capsule three times a day."
