Hi, I've been taking gabapentin for about 10 years and find it to work very well for my pain associated with fibromyalgia and nerve issues due to spinal stenosis. I can tell you that on the rare occasions when I've forgotten to take it at night, it has kept me from a peaceful night's sleep (my nerves seem to be tingling) plus I wake that morning with nausea, fatigue and sometimes a headache. I just try to never forget my medications.

I have weaned myself from gabapentin in the past, leaving off just one pill at night for a period of 5 days before i leave off another. I've found it to be very uncomfortable, but it doesn't seem to last more than a few days. I hope this helps?
