I am on 20/4 amitriptyline /perphen azine. I have been on it for about a year for depression and anxiety. It does not work for me I have tried to go down to 10/2 and 15/3. Both of these produced intolerable anxiety within hours of missing a full dose. I lasted 2 days on both of these amounts then ended up going back up to 20/4 Any suggestions what I might do I really want off it so I can try something else
