Dear Canagirl,
I am currently taking 20 mg amitriptyline at bedtime. I have been taking for it for about 3 months. At first it made me very drowsy and I was finally able to get some sleep. I have noticed that I am not getting as much relief from it now and may need to increase the dosage. I have acute onset but now chronic progressive idiopathic small fiber predominant mixed sensory-motor polyneuropathy. I have tried Gabapentin and Topamax and could not tolerate. The withdrawal from Topamax was horrible. During the day I take 1-2 Vicodin as needed. I have a follow up visit with pain management Dr. next month to discuss options. My symptoms have progressed to my arms and trunk recently and it is a scary feeling. I hope this helps you. You are not alone!
