Hi, I have been prescribed Amitriptyline for migraine induced dizziness and I have GAD too. I started on 5mg as couldn't take the side effects on 10mg. I got used to it after a week but had a dizzy spell on Friday so decided to go up to 10mg but after 2 nights I feel SO groggy and so dizzy I can hardly walk in a straight line and terrified I am going to pass out at any moment. I dont know if to go back to 5mg or just stop (but that would waste the pain I went through last week with the side effects. Or do I keep going with the 10mg and hope I get used to it. I didn't take 1 last night and feel just as dizzy today. Feel totally stuck - help please....thank you x
