I used to take 50mg amitriptylin as prescribed by my doctor, but this new doctor prescribed it to me at my request because it worked really well -- we weren't sure what the original dosage was at the time, so she started me out on 10mg. She wasn't really clear about whether or not she wanted me to take my valium with it, though, and I know they both make you drowsy so... probably one of those interactions you have to worry about, right? The valium's really helping with my anxiety, but the amitriptylin really helped with my depression. I don't know if I should be taking both or if I need to choose one or the other.
