Gabapentin
"I have had GAD ever since I can remember and I am 31 now. NOTHING and I mean NOTHING helped. My anxiety was so extreme, every minute of every day I was consumed with it. I had severe panic attacks and would sometimes faint. Gabapentin has been life changing for me. I have been on it for 3 months and my GAD is almost gone. I still have panic attacks at night, but this medication has been a miracle for me and I am and would definitely recommend trying it, specially if you are not responsive to 'normal' anxiety medications."
