"i&#039;ve been taking gabapentin for three years to relieve my anxiety symptoms; 1800mg twice daily. although i started at a much smaller dose in the beginning and did feel groggy at times my body is now completely accustomed to it. this is the only medication i have tried that allows me to function normally on a daily basis without feeling side effects. i highly recommend it to patients with gad who don&#039;t respond to other medications."
