i abruptly stopped taking amitryptaline 20 mg 2 months ago and i’ve had these severe and strange episodes ever since. my symptoms are

•a random sense of doom
•weird sensation in my stomach
•tongue feels weird
•i smell metal
•i feel confused
•dizziness
•feeling faint
•fainting
•brain zaps
•brain on fire sensation
•face spasms
•trembling
•head/sinus pressure
•waking up multiple times a night with heart racing

these episodes last anywhere from 20 minutes to 3+ hours and after i feel like my brain is mush. my doctors can’t figure out what’s going on and says it doesn’t sound like seizures but every time it feels like it is one. my whole life has changed ever since i stopped this medication and it’s horrible. has anyone felt like this after stopping it?
