Day 3 and struggling

I had my first 2.5mg dose Thursday. I felt fine Thursday and yeaterday. Last night I started getting sulphur burps (which was the side effect I was fearing most due to past issues with sulphur burps) but they weren’t too bad and some peppermint tea was keeping them at a cope-able level and I threw up a protein shake. I woke up at 7am this morning with bad stomach pains all over in different places, indigestion, really bad sulphur burps, vomiting and now diarrhoea and a bubbly gut. Currently waiting on Amazon to deliver my remedies that I got after researching things to ease it. I am feeling exhausted!! Is this just gonna last a couple of days or should I expect this to last for the next few months? What’s your experience? Any advice and tips would be most welcomed too. Thank you ❤️
