I have been taking 10mg of amitriptyline for over a year for migraine prevention. After missing doses (probably 5 doses) in November while out of the country, I noticed feelings of anxiety, shortness of breath, and chest tightness. I started taking my medicine regularly after this, and the symptoms slowly went away.
This past weekend I missed a dose after a night of drinking. Since that missed dose I have been taking it normally, but am experiencing the same symptoms that I did in November. Is it possible for me to experience withdrawal symptoms after only missing one dose? If so, how long should I expect symptoms to last?
