"i have been on gabapentin for about 2 years. i had severe anxiety and tried amitriptyline and citalopram without success. i take 3 x 300mg gabapentin a day and my anxiety has certainly decreased quite significantly. i still have the occasional &#039;black cloud&#039; day, but i can honestly say these tablets have definately tsken the edge off it. i sleep better, have not gained weight and do not feel like a zombie. for me, gabapentin has been a good alternative to usual antidepressants."
