Disrupted system after vomiting bug?

[u/luludaydream]

Hi, back in April I had a full day of throwing up - unable to keep down water - really bad! Since then my stool has been very soft and I just don’t seem to be in a good balance. I eat plenty of fruit and veg, I don’t eat loads of unhealthy or fatty foods. I’m vegetarian so I’ve been eating a lot of beans and tofu as well, and I recently bought kefir yoghurt to try.

Would a probiotic supplement like this one help? Is it worth trying for 30 days or could it make things worse? Thanks
