Sertraline and digestive issues🙄

Hi folks. Started sertraline a month ago (had tapered off it few months back but unfortunately relapsed). I started on 50mg with an increase of dose to 100mg just over 2 weeks ago. Last few days I have been really troubled with an unsettled stomach and terrible indigestion which is making it harder to eat. I take various supplements including a multivit and probiotic. Anyone any expertise on other measures to counter act the indigestion and washing machine stomach? In the meantime I'm off for a peppermint tea... And perhaps some grinding of teeth😬😬thankyou xxx
