You can take 10 puffs of the Ventolin, but if things are getting this bad you do need to go and talk to the professionals really...
(mosschops - DS (11mo) was in paeds with viral wheeze last week - the nurses refused to believe the registrar had prescribed only 8 puffs of Ventolin (because of tachycardia) and got another doctor to change it to 10 puffs)
One glass of wine won't put you over the limit, especially not 5 hours ago. Assuming you're not drinking wine out of a pint glass of course!
