I’m so sorry. I have not experienced anything like that! I have taken a medicine called Dicyclomine for abdominal muscle spasms and did notice that taking it after eating really helped me for a while!

I’ve found supplanting magnesium to help when my muscles get tight, when I don’t take it I have tightness on my whole left side from my pinched nerves that often ended in spasms and cramps . With the extra magnesium, even if I’m not taking my constant other electrolytes for my suspected POTS, it keeps the tightness way down to a more tolerable level. Just be careful which magnesium supplement you choose, some are laxatives. I take magnesium oxide.

I take magnesium glycinate and citrate for sleep, headaches, and just in general no side effects at all… haven’t really noticed any help though either but know it’s not hurting me
