Weird 2nd Month Symptoms

I am on my 3rd shot of .5 and I wanted to see if anyone else has been having similar symptoms. At this point I can really only eat saltine crackers, rice, chicken, and salmon. Red meat, anything with a decent amount of added sugar, most dairy products, pastas, most everything else makes me so sick! It starts as nausea, then stomach cramps/gas pain, then come the burps! They are awful! Uncontrollable burps that just come out, and they smell and taste horrible! I’ve researched a little bit, and I think they are sulfur burps. Over the last 2-3 weeks, I have had 3 days of peace. The rest I have been sick. Has anyone else experienced this? If so, what helped?
