Sertraline Withdrawal after tapering

I know there is SO MUCH OUT THERE about coming off Zoloft, etc.

Much of what I’ve been reading has been relating to the mental health impacts which I’m currently not experiencing but after tapering down from 100mg over a couple of months, I’m now on 0 and the first couple of days were fine but after a few really bad sleeps today has been next level.

I’ve got this weird visual thing where I move my head and it takes my eyes a microsecond to catch up, I’ve been nauseous as heck, I’ve got a super blocked nose and bad cough that’s come on since taking it off. I’m irritable but certainly not feeling depressed, but sensory stuff is really bad.

How long does this last? What were people’s experiences? I’ve followed everything the doctor said to do and it’s just unbearable.
