Hi,
I had a stomach bug last month which really knocked me off my feet. Since then my stomach hasn't been right. I've been really sensitive to strong foods and would often randomly get diarrhea that would suddenly come on. Being in a family who deal with different intolerances I cut down on the gluten and lactose, making notes if I did eat a little more to see if it made a difference. It didn't seem too.

The last week however, it seems to have gotten worse. I can be fine in the day and about 8pm I start feeling nauseous. I've woken up 3 times in a row at roughly 3am to be quite violently sick.

What could cause this? Any natural remedies before I bother my GP?

Thank you
