ibromyalgia
"I was prescribed gabapentin for fibromyalgia 3 weeks ago.. taking 300mg 3x a day after years of trying every depression medication and being in pain killers for back pain for a year. I was consistently unmotivated.. I didn't want to do ANYTHING, had severe body aches, and generally felt like crap with depression and anxiety to top it off! 
After my first dose of 300mg I felt better within the first 10-30 minutes. I got up and felt like I had purpose.. my anxiety and depressed ceased and my body felt better. 
I would recommend this to anyone unless you have problems with weight gain. It seems to cause water retention. Also, sometimes I get dyslexic or clumsy.. those are the adverse effects for me, not sure about anyone else?"
