Sulfur burps followed by vomiting, sometimes diarrhea...probiotics?

[emx2]

Whenever I get the stomach bug or am going to throw up, it always starts out with sulfur burps. The burps get worse and worse until I get nauseous and throw up. I have been taking Align probiotic for 5 years or so. At one point I tried to see if I could get off of it, so I stopped taking it. However, I then experienced sulfur burps and vomiting and went back to taking the probiotics daily. Within the past 3 or 4 months, I decided to start taking the probiotic every other day. Since then, I have experienced about four episodes of sulfur burps and vomiting, sometimes with diarrhea. I am wondering if this has to do with the probiotics. Sometimes I am not perfect with making sure I take the probiotic every other day, so I occasionally may take it once every two days. I also recently completed a Whole30 and in the middle of it, I had an episode. After some thought, I am wondering if anyone has any thoughts on the connection between probiotics and sulfur burps/vomiting? I had an episode today (2 weeks since my last one) and I really don't think it has any connection with the food I am eating. I am going to go back to taking my probiotic daily to see if that helps. Please leave any thoughts you may have!
