Hi, I Have Fibromyalgia And My Neurologist Has Prescribed Gabepentin,

Hi, I have fibromyalgia and my Neurologist has prescribed gabepentin, startin with 100 mg 3x a day for 2 weeks, I have been been affected with constipation since the first pill. I have only taken 2 a day because of that and have now worked my way up to 3 a day, starting yesterday. Today, my hands are shaking. Would the gabepentin cause this?
