Gabapentin
"I have been prescribed Gabapentin for insomnia. For the last 2 years I have taken it nightly at bedtime 2000mg + 12.5 mg zolpidem ER + .25 mg of alprazolam.  I find the zolpidem + alprazolam put me to sleep and the gabapentin keep me there...... most of the time.  I feel as though I have forgotten how to "fall" asleep, but now knock myself out.  After taking this handful of pills nightly at 9 PM, I can be awake at 2 am or 4 am. It has been a lot of drugs for a long period of time.  Since the drugs "labeled" use is for nerve pain, which I didn't have, I worry that the neuroma in my foot that developed 15 months ago might be related.  Neuroma, foot injections, foot surgery .. Pain unresolved

How effective do you think it is?"
