that's its generic name, and those are some brutal side-effects tbh (zoloft does the "brain zap" thing if you're dropping it without easing out/replacing it with something else, but it happens months or like years into being on it, not during the early adjustment stage - that's absolutely not normal),
which is also an example of how powerful this stuff is in a negative way when for some reason your brain chemistry doesn't agree with what the pills are producing.
I hope you found a better alternative for it, there're newer (and for some people way better) alternatives too.
there's no real benefit in sticking to something that makes you feel awful while you still have options - however your dr might not be too inclined to offer them for like their own personal reasons, which was my point. it's not immediately obvious that sometimes you will be better off just talking to a dr that takes your complaints more seriously, given the amount of various biases that potentially contribute to their assessment.
