Metformin intolerant

Hi guys. In Dezember I started taking metformin 250mg. Then after a week I startet taking 500 mg once a day. 250 morning and 250 at night. After 3 weeks I started shaking, feeling dizzy and very very sick. I was even at the hospital to get tested for Laktatazidose. It was negative tho

I immediately stopped taking it but still had panic attacks. I thought I was never gonna feel well again. It went away after a few weeks, but to this day, I feel sick very easily when I eat something

Do you have any tips on how to try it again. I’m lowkey traumatised from that experience
