Should one reduce by 100 mg at a time for how long before reducing another 100 mg? I'd like to try to eliminate this drug if possible. I have been taking it for sciatic for approximately 8 years when I started with 100 mg t.i.d. Allergies and Asthma with shortness of breath and constant coughing day and night--wondering if those symptoms are stemming from increasing doses of Gabapentin.
