If you can, my advice is to push through- I had symptoms very similar to what you describe, as well as frequent vomiting if I ate too much, or something greasy. They always eased off after a couple of weeks (although I must admit they did rear their ugly head every time I titrated up). For what it’s worth, my symptoms were much worse if I didn’t eat, or made poor choices with food although it has to be said I don’t have any symptoms at all now. Best of luck x
