Hi
@CatLadyNZ
I wonder if this could be down to stopping the Amisulpride. I was on Sertraline last year and on the odd occassion when I ran out...for whatever reason (I'll not have that particular moan up right now) I experienced exactly the symptoms that you're describing...nausea...dizziness...it was quite a strange sensation and quite hard to describe. Although you say you were only on a small dose and it's a completely different drug it may still be worth reducing slowly.
I've copied a little info from found online re Amisulpride withdrawal....
Acute withdrawal symptoms including nausea, vomiting and insomnia have very rarely been described after abrupt cessation of high doses of antipsychotic drugs. Recurrence of psychotic symptoms may also occur, and the emergence of involuntary movement disorders (such as akathisa, dystonia and dyskinesia) has been reported. Therefore, gradual withdrawal is advisable.
Hope you get to the bottom of it
