Flu? Stomach bug? Food poisoning?

So last night at around 3am I woke up feeling like I was going to throw up, I didn’t in the end and managed to get back to sleep.

I didn’t eat breakfast but I did have a latte and with about an hour or so I felt really sick and in then threw up. I have tried eating some plain pasta and let’s just say I no longer have that in me .... I did have 3 loose bowel movements as well but nothing too major.

I have been drinking water all day and can’t even keep that down it’s now 12 hours later and still throwing water back up.

Any suggestions as to what this could be ?
