i have this issue too but this particular issue started after mirtazapine and amytriptyline. im not sure which triggered it but i think it was amytriptyline.
be careful with mirtazapine, it will exacerbate this.
i am still trying to figure out WHY this happens.
im not sure what is going on…after more than one year of reading, researching and trial and error, i’m left with these:
- high norepinephrine or adrenaline…increased to counter histamine released by mast cells either due to excess estrogen or some allergy to food or to some excipient of medication…
- low dopamine caused by increased serotonin either from meds or something else, leading to Periodic Limb Movement Disorder or some form of it
- low dopamine caused by acetylcholine imbalance
- low GABA
- Inflammation on nerves
- some problem at androgen level
I think the problems lies most probably at the dopamine level because when I was a kid I took Metoclopramide (an antidopaminergic) for a stomach ache, only once, and it triggered epilepsy the very same night. I’m sure they were epileptic fits as I have the wave pattern EEG on paper indicating epilepsy. I have since 14 been med free,asymptomatic, and EEG has been fine (repeated 2 years ago) , but now I have insomnia and these very same reactions you post: brain zaps, waking up with rapid heart beat and a jolt as i drift of to sleep, finger moving, finger twitching, as i drift off to sleep.
Do you have the results of any exams you did??
If you find a solution for this, or a reason, please come back and post it!! this is killing me.
