Does anyone have any experience with amitriptyline? I've been on it for maybe 18 months and it's been good for relieving pain, but recently I've really struggled with my memory. I can forget something important, like who is picking my DC up from school, an hour after I've made the arrangements. I was wondering if I need to try something else to help manage my chronic pain. I also take gabapentin and cocodamol. I've got some kind of neurological condition (not MS) that causes nerve pain and weakness on one side of my body.
