Amitriptyline
"Dear God thank you!!!!! PTSD causing insomnia and crippling panic attacks!! Have been on every SSRI made the panic worse! Basically I just can't take SSRI and SSNRI.  They led me to panic disorder as if anxiety and insomnia weren't bad enough. I suffered for ten years until I crashed  Then I started 0.25 immediate relief! By 8 weeks no panic and by 9 weeks I am sleeping. I have no side effects for me other then next day brain fog.  Just kind of like duhhhhhh lol it went away. I should've, could've and wish I  would've a done this sooner!!! Very cheap older med of the tryclic antidepressants. I also tolerate trazodone hence my PCP going for this ! Never give up peeps!!"
