I had a tummy bug 2 weeks ago, diaohrrea but no sickness, just feeling sick. It stopped after a few days but my tummy hasn't properly recovered. I still feel sick off and on and very gassy and uncomfortable. Especially towards the end of the day. What can I do to try and recover? Is the brat diet still a thing? Prebiotic yogurts? Or just starve myself for 24 hours? It's doing my head in now! Thanks
