Awful nausea on minastrin

I'm reaching towards the end of my first pack of these. Although I've been getting really nauseous and bloated. I laid off junk food and such and switched to drinking just water (that usually solves  the bloating.) but I matter what I do I have think blanket of nausea over me. I'm not pregnant. How do I stop this? It's starting to interfere with my day! 😐😪 any ideas? Suggestions?
