Gabapentin
"Gabapentin, for neuropathy, not diabetic, a smoker, treated with interferon for 13 months. I am female, 65 years of age. Dosage, 800 mg, 4 tablets a day.  It did help with the neuropathy, I noticed no side effects.  Then I read that Gabapentin could attribute to weight gain if taken with prescription pain medication.  So, I quit taking it cold turkey.  I was not informed by my neurologist to not just stop taking this medication.  

Within a few months I became ill. I was fatigued, couldn't think or remember properly but, didn't know what was wrong with me.  I was fired after 6 years of service.  One day I decided a gabapentin would help. Within 30 minutes, I was Marlyn again and overjoyed. I have since read withdrawal can take up to a year."
