Im same as "cant stop crying" I went from 150mg of effexor to nothing, and its the only time Ive had brain zaps, I cant really explain them kind of like a small voltage of battery, I was scattered and absent obviously, I think I remember telling myself not to panic maybe experienced 10 a day for the first 3 days then less and less. I had dizziness at the time too, my partner had just given birth to our first child, I was all over the place, but I dont think the zaps are uncommon as I remember the mental health nurse new what I was talking about when I described that symptom.
It would be best to check with a psytrist as they are obviously a warning sign of some sort...
