I was given Neurontin to try and help with my fibromyalgia . I was initially given a titration pack to build up the dose until i felt pain relief . I reached the stage where i was taken 1800mg a day (3x600mg) and simply couldn't function properly and still with no pain relief . I literally felt spaced out all the time , couldn't remember where everyday household items belonged , and would regularly have severe memory loss during mid conversation . Nothing seemed to sink in when i was told something . i have started the process of coming off these tablets , i have enough problems without adding to them .
