Poorly Scooter-boy - please advise!

DS, 10 months, was sick when he woke up this morning, sick again after his breakfast and had a rather runny nappy.
He hasn't got a temperature according to the ear thermometer but is quite sleepy and quiet.
Should I rake him to the docs or is it just a tummy bug? The sleepiness does worry me slighly.
Has had nurofen about 20 minutes ago.
Thanks x

I'm very cautious cos he ended up in hospital with suspected meningitis when he was eigth days old so I'm entitled to be over-protective!
The no-temperature makes me thnk he's probably ok but the dopiness is a bit disturbing. He didn't even want a biscuit earlier (the true test of illness in our house for both DCs!)
