Personally, I wouldn't, LCG. Try some toast first & try and drink a little water.
There have been a nasty tummy bug going around my grandson's school last couple of weeks. Hope you feel better soon.
The painkiller that's used in hospitals nearly all of the time, simply because there are very few situations where it's not appropriate, is paracetamol. So that's what I'd opt for in your situation.
lcg - my stomach has been in knots for about a week and half - not a tummy bug but lots of anxiety.
haven't been eating well either but after having a slice of toast this morning - more or less forced myself to have two fish fingers. You need to eat with ibuprofen. And also drink plenty of water.
