"i have been on gabapentin for two weeks now. i&#039;m on 300mg three times a day. it took about a few days for it to start working. but i have to say that this med works! if i do not take it or if i&#039;m getting close to my next dose. i start to feel depressed. i love taking this. it really does help for headache pain, and mood. i got this for depression. because i do suffer from depression and anxiety a lot. it seems to help with the depression but not anxiety. if anything it makes me more happier. more calmer and more relaxed. i have gotten dependent on this drug for my mood. it doesn&#039;t make me sleepy at all. my body has gotten use to taking it. i don&#039;t see myself getting off of this. i enjoy being relaxed and feeling calm."
