Amitriptyline
"I was put on Amitriptyline 10mg to help with severe back pain and trapped sciatic nerve affectng the lower right leg very badly. Had to stop driving.  I started to sleep extremely well but had not really had much pain to cope with at night so there was nothing special to note there. Daytime pain seemed unchanged until about 5 to 6 weeks into the course I did notice that daytime pain had lessened.  However I also noticed that in weeks 6 to 7, I was feeling extremely low, depressed, lifeless and started to have dull headaches, reread the side effects and decided to stop the drug immediately. I am a different person, feeling so much more alive and for me, the drug caused an effect more serious than the back and leg pain."
