I have been on 10 mg Elavil for about 2 years. Unfortunately didn't help with my main symptoms (dizziness, headches, fatigue) for me and some things it helped is to make my stomach calm and helped with my smell disorder. As mrsD mentioned nowadays it has been used for number of reasons and for some it helped immensely with PCS.

Each person is different when it comes to how you react to medicine and some has no side effects and for some significant. It made me more dizzy in the beginning then side effects went away. Same goes for quitting. I tried to quit and it affected my sleep, got terrible nausea than normal. I guess I continue for now. according to doctors 10 mg is really a low dosage.
