Hello again.
I just cut and pasted this for you. This comes from a publication from the Harvard Medical School.

*** The last item talks about "brain zaps" which, I believe, you described this in your post.

I quote here:
"Neurotransmitters act throughout the body, and you may experience physical as well as mental effects when you stop taking antidepressants or lower the dose too fast. Common complaints include the following:

Digestive. You may have nausea, vomiting, cramps, diarrhea, or loss of appetite.

Blood vessel control. You may sweat excessively, flush, or find hot weather difficult to tolerate.

Sleep changes. You may have trouble sleeping and unusual dreams or nightmares.

Balance. You may become dizzy or lightheaded or feel like you don’t quite have your “sea legs” when walking.

Control of movements. You may experience tremors, restless legs, uneven gait, and difficulty coordinating speech and chewing movements.

Unwanted feelings. You may have mood swings or feel agitated, anxious, manic, depressed, irritable, or confused — even paranoid or suicidal.

Strange sensations. You may have pain or numbness; you may become hypersensitive to sound or sense a ringing in your ears; you may experience “brain-zaps” — a feeling that resembles an electric shock to your head — or a sensation that some people describe as “brain shivers.” " end quote
