I take amitriptline for neck pain.I have 2 prolapses and it is meant to numb nerve endings. The only thing i did wrong with it was to go from 200mg to 50mg in 2 days.That was when my panic attacks really got bad.I have had to down it gradually and have finally gotten down to 100mg.I will never stop this medication as my dr assures me i can be on it for life.Phew!!1 It does worry my hubby though as he thinks i should be trying to get off it but i have major panics thinking about this.It does help you to sleep.
