"i have had chronic cluster headaches for years-and generalized anxiety disorder, panic attacks and was diagnosed about a yr and a half ago w bipolar 2  neurontin was given to me for nerve pain which it didnt help. but- for anxiety, panic, living with a feeling of constant uneasiness and dread... it is life-changing for me.  i no longer have to live that horror. it honestly was a horror.   so this is what living feels like!!!!!!  i am unable to express my gratitude to the dr that prescribed this to me. absolutely life-changing   if you suffer from any of the forementioned conditions- its worth trying. it works within 25mins of taking it. theres no prolonged waiting period.  i take 800mg 3x day."
