Taking gabapentin 100mg 3 times a day and having chronic kidney disease stage 3. Is this OK?

I also have stage 3 kidney disease. My doctor has me take only 2 a day, one morning and one night, about 12 hours apart. Could you manage a reduced dose?

It is very hard to answer this question. You need to do some test to take this medicine but following article may help you understand the risk of taking gabapentin:

Gabapentin toxicity in patients with chronic kidney disease is under recognized. Patients with chronic kidney disease often receive inappropriately high gabapentin dosage for their kidney function, occasioning overt toxicity; advanced age and comorbidity predispose these patients for toxicity. Heightened awareness of such preventable risk, amid the chronic kidney disease epidemic, would be cost-effective and improve health care quality.
